excessive shock loading and may result in serious
damage to the crusher.
All hydrocone crushers are supplied with a feed
hopper with an adjustable feed spout that is adjustable
both vertically and horizontally. Horizontal adjustment
of the spout is accomplished by moving the adjustable
feed spout frame on the feed hopper. Slotted holes in the
upper flange of the feed hopper, and in the feed spout
frame, allow the feed spout to be moved horizontally in
order to position it properly over the feeder plate or
spider cap. The feed spout can be positioned vertically
by using studs and adjusting nuts to fasten the spout to
the frame. The vertical position of the spout controls the
amount of feed going into the hydrocone crusher.
Adjustable feed spout frame construction allows the
mounting of a suitable feedbox. Normally, it is better to
have the incoming feed hit the side of the feedbox, after
which it falls vertically through the feed spout. This is
the most effective way of obtaining proper feed to the
hydrocone crusher (fig. 6-8).
The discharge arrangement setup must allow the
material to discharge freely without backing up
underneath the crusher. Material backing up below and
into the hydrocone crusher can result in serious damage
to the machine.
A straight-down discharge is commonly used with
hydrocone crushers. With this arrangement, crushed
material falls into a stone box below the crusher.
Material passes through a hole in the stone box floor
onto a conveyer belt that carries it away. This discharge
arrangement helps prevent buildup of sticky materials
beneath the crusher.
The crushing chamber is annular (ring shaped).
Rock fed into the top falls between the cone and
the mantle and is crushed as the opening narrows with
the movement of the cone. When the opening widens
again, the pieces fall farther, to be crushed again
as the cone gyrates. The crushing action is similar to
that of a jaw crusher, except the squeeze comes from the
side rather than from the bottom and the curve of the
The cone speed and the distance of travel must
be carefully synchronized. A wide space allows
pieces to fall more freely than a narrow one when the
cone is moving slowly; however, it allows pieces to fall
too far before the next impact. On the other hand, where
the space is narrow and the cone is moving rapidly,
the pieces cannot fall far enough and this causes
production to be low for the amount of power being
DO NOT operate the cone crusher at a
smaller setting than that for which it was
designed. Operation at too small a discharge

Dynamism builds business as minerals are crucial elements for high-tech development
The unveiling of China Rare Earth Group Resources Technology Co Ltd will effectively bolster the growth of China’s rare earth metals industry and provide impetus to companies from smelting processing to technology research in the years to come, analysts said on Thursday.
The comment came after China Minmetals Rare Earth Co Ltd, a subsidiary of China Rare Earth Group Co Ltd and a Shenzhen Stock Exchange-listed company, changed its name to China Rare Earth Group Resources Technology Co Ltd. It aims to realize the high-quality development of the rare earth metals industry and strengthening its brand impact and market influence.
The move marks a new stage in the integration of China’s rare earth industry, said Weng Jieming, vice chairman of the State Assets Supervision and Administration Commission of the State Council, the country’s top state asset regulator.
This will help China Rare Earth Group Co Ltd, a centrally managed state-owned enterprise based in Ganzhou, Jiangxi Province, to further enhance the concentration of the country’s rare earth industry, consolidate the asset quality of listed companies and facilitate integration of industrial management and capital operations, Weng said at the inauguration ceremony for the new company on Wednesday.
In addition to the name change and equity integration, China Rare Earth Group Co Ltd will better connect the upstream and downstream sectors of the rare earth industry chain and help promote the upgrading of traditional industries and the development of strategic emerging sectors, said Ding Rijia, a professor specializing in mining economics from the China University of Mining and Technology in Beijing.
Established in December 2021 jointly by three companies – Aluminum Corp of China, China Minmetals Corp and Ganzhou Rare Earth Group Co Ltd – and two research companies, China Rare Earth Group Co Ltd’s business mainly includes exploration, exploration, smelting and Deep processing of rare earth metals.
Business lines also include downstream applications, equipment manufacturing, industrial incubation, technical consulting services and foreign trade.
Ao Hong, chairman of China Rare Earth Group Co, said the group will strive to build the newly listed company into a leading listed company in the industry with remarkable professional merits, great market influence and strong core competitiveness.
Rare earth metals are important strategic resources and key elements in the development of high-end technologies and green applications. These are highly valued by various technologies, from wind turbines to mobile phones to LED light bulbs and televisions.
China is the world’s largest exporter and reserve holder of rare earth metals. Its exports of rare earth minerals rose 5.7 percent year-on-year to 33,539 tons in the first eight months of this year, statistics from the General Administration of Customs showed.
As the government is determined to undertake deep integration of the same or homogeneous companies into its core SOEs, it has already accelerated the building of world-class groups with strong profitability and optimal resource allocation in key areas such as inspection and testing. Medical and healthcare, device manufacturing, artificial intelligence, new energy, cloud computing, steel, logistics and other strategic and emerging industries.
“As the scope for reducing the number of key SOEs through mergers and restructuring is limited, the government is more inclined to integrate its companies to better optimize resource allocation,” said Xu Baoli, a researcher at SASAC’s research center.
Thus, at the end of August, two subsidiaries engaged in testing and inspection business, previously owned by China General Technology (Group) Holding Co Ltd, were merged by China Certification and Inspection Group.
COFCO Group and China Grain Reserves Group Ltd also established a new company – China Enterprise United Grain Reserve Co Ltd – in mid-August to manage the country’s grain reserves through equity cooperation.
Li Kongyi, an analyst at Shanxi Securities, predicted that there will be more reorganization and integration moves at key SOEs in the coming years. Based on the needs of national opening-up policies and economic growth, the restructuring of core SOEs in industries such as energy, automobile, transportation and military will be accelerated.


About Synergen Met
Synergen Met Pty Ltd is an Australian-owned and operated business made up of a team of scientific minds with more than 80 years of experience working within the global mining industry.
Synergen Met was formed seven years ago to develop the technology for a modular sodium cyanide process plant, the Synergen NaCN Plant , invented by Dr Geoff Duckworth.
The Synergen NaCN Plant is a world-first technology that has been invented, developed and tested from the ground up to meet the precise needs of the world's gold, silver and base metal mineral processing operations.
The first plant of its kind is located at a mine in Australia and it has undergone more than six years of rigorous development and testing with some of the industry's brightest minds.
The Synergen NaCN Plant is a modular, stand-alone production plant for the manufacturing of sodium cyanide. Each plant is the size of a standard 40-foot shipping container and is readily transportable.
We believe the Synergen NaCN Plant will cause a major shift in the approach to cyanide production and management in the mining industry. It is designed for a just-in-time production approach and this is the catalyst for a wide range of environmental and economic advantages.
The plant will eliminate a range of dangerous activities associated with the use of cyanide such as transportation, on-site handling, and maintaining large cyanide inventories.
The plant's technology has been through the PCT patent process and full patents have been granted in Australia, Mexico, South Africa and the two African patent regions of OAPI and ARIPO. Patents are under review or are near to review in the USA, Canada and Europe.


The paradox of Sierra Leone is that it is one of the poorest countries in the world yet it has abundant resources and possesses some of the most commercially valuable mineral reserves in the world. The country is (i) among the world’s top ten diamond producing countries; (ii) one of the largest rutile and bauxite producers; and (iii) a major producer of gold and it has the second largest iron ore deposits in the world. The recent announcement of off-shore oil reserves is an addition to the country’s considerable mineral wealth. Sierra Leone is one of Africa’s seven mineral dependent states. Its dependence on the mining sector is reflected in the sector’s historically high contribution to GDP at 20 per cent and registered exports at 90 per cent, especially during the late 1980s and early 1990s. Mining and quarrying provided a livelihood for more than 250,000 people, and employed about 14 per cent of the labour force during the period.
The importance of the mineral sector to Sierra Leone is further exemplified by its role in the brutal civil war that was partly fuelled by some of the mineral resources, particularly diamonds. Diamonds became the key source of revenue for the rebel groups to procure weapons and ammunition. This allowed them to control mining areas under them and to further expand their territorial control over such areas and the mines, which they exploited for their own economic gains. This created a spiral effect as the rush for minerals became a motivating factor for armed groups to further fuel the war.


Horrific Coal Mining Accident in West Virginia

|Metals and alloys (a mixture of two or more metals) play a fundamental part in the structure of the modern world, but the use of metals by man dates back to prebiblical times. The first metals used were those that occurred naturally and appeared on the Earth\'s surface such as gold, silver, iron and copper. These supplies were soon exhausted, and it was not until the Bronze and Iron Ages that it was discovered how to extract metals from their ores, where the metal is chemically combined with other elements such as sulphur and oxygen. As dependency upon metals grew, the techniques to locate and recover the metals from their ores became more sophisticated. Such metals as copper, zinc and lead are extremely rare in the Earth\'s crust, but they have all become an integral factor in today\'s society. The availability of ores depends not only on their scarcity but on how easy it is to extract and exploit the ores.
The use of iron and steel account for around 95% of all metal products in the Western world. The process of reducing iron oxides to metallic iron is smelting. This involves heating the iron ores along with carbon to produce carbon dioxide and iron. This process was carried out using charcoal until Abraham Darby (1677 - 1717) succeeded in smelting iron from coke (which could be easily produced from coal). This raw iron or â€˜pig ironâ€™ (so-called from the shape of the lumps produced by the process) can be melted again to remove impurities and have carbon added to it to produce steel which is much stronger and can deform more before breaking. Cast iron is very brittle and snaps with little deformation. Steel may have other metals added to it, in order to produce alloys that have very useful properties. The addition of nickel and chromium is used in the manufacture of stainless steel, while the addition of cobalt, molybdenum, tungsten or vanadium produces hard-wearing steel for cutting tools.
Although iron has been used for over 4,000 years, the most common metal found in the Earth\'s crust, aluminium, was only isolated for the first time in 1825 by the Danish physicist Oersted. Aluminium has many uses such as thin foil sheets for food wrapping, the structure of aircraft and in the electrical supply industry as transmission lines.
Another metal in common industrial use is copper and its alloys such as brass and bronze. As well as being a good electrical conductor, it is also used in coinage and in plumbing. Other metals such as gold, silver, tin, lead, chromium, mercury, platinum, magnesium and zinc all have their specific applications, but probably the use of uranium in nuclear power stations causes more controversy than the use of any other metal or alloy.
Metals are being used at an alarming rate as the Third World countries try to catch up with the rest of the world, and the supplies of such scarce metals as silver and platinum are in doubt. A substitute material may be found in order to compensate for such scarcity, but this may not always be possible. Another factor to take into consideration is the fact that as technology becomes more sophisticated the extraction of scarce ores may become viable in the future. AA

Republic of Mali is a landlocked country in West Africa. Mali is the eighth-largest country in Africa, with an area of over 1,240,000 square kilometers. Mali is bounded on the north by Algeria, on the east by Niger and Burkina Faso, on the south by Côte d’Ivoire and Guinea, and on the west by Senegal and Mauritania. Gold mining in Mali has a long history, noted from 1433.
IDERA Mineral Resources has started prospecting in Mali, which is among five largest African gold producers, after Ghana, South Africa, Sudan and Tanzania. Idera’s initial exploration works in Mali conducted in early 2020, but not with expected progress, due to numerous problems caused by Coronavirus.
Gold reserves in Mali are easily accessible with open pit mining operations, which makes operation costs much lower, which means that lower grades of ore are economical to mine. Also, highest grade gold in Mali mines goes from 2 grams per ton to 5 grams per ton, which takes Mali to the top of the West African list of the highest grade gold producers.
Idera commenced prospection works in south Mali, near to the Burkina Faso-Mali border and Côte d'Ivoire-Mali border, approximately 400 kilometers south of Bamako, the state capital. Prospection areas are located in gold Sikasso region. This region is made up of a volcanic (andesites, dacite, etc.) and volcano-sedimentary (metagreywacke and tuffs) sequence of Birimian rocks, widely known as gold prospective.
The Birimian rocks display similarities to archean greenstones, which are one of the main sources of gold in the world. They are major sources of gold that extend through Mali, Ghana, Côte d'Ivoire, Guinea and Burkina Faso. Birimian consists in supracrustal rocks (volcanic greenstone belts and sedimentary basins) and TTG gneisses, granitoids and granitic intrusions of different ages. Deposition and emplacement of Birimian rocks date from 2230 Ma to 2060 Ma (for younger magmatic rocks).
In the south Mali, in perimeter of about 250 km there are numerous gold mines and deposits, including Syama, Morila, Kalana etc. and dozens of gold showings which belong to Eburnean orogenic domain who has created Birimian rocks. In this region, beside mines there are artisanal mine workers who have great mining results. All those gold indications and results were tremendously helpful in our prospection and target decision making.

Nearly 50 years after the passage of the federal Coal Mine Safety and Health Act, significant occupational dangers for coal miners remain. As the anniversary of the Sago Mine Disaster approaches, and on the heels of the 50th anniversary of the Farmington Mine Disaster, Michael McCawley from the West Virginia University School of Public Health notes black lung cases are on the rise and silicosis diagnoses persist. His research has been inspired by these and other mine tragedies in an effort to make coal mines safe and healthy places to work.
On researching mine safety: “This past year, I served on a panel for the National Academies of Sciences, Engineering and Medicine, investigating why more and more miners are contracting black lung disease. We concluded there was likely a gap in the administration of coal-mine-dust regulations, especially those that covered slope mining, a kind of mining that may involve cutting a lot of rock to reach a deeply buried coal seam. Rock contains silica. Cutting it generates dust that is toxic because of its silica content. Inhaling this toxic dust is likely partly—or totally—responsible for black lung. But companies only have to sample dust when they are extracting coal, not as they are cutting the rock to access it. That means the period when silica exposure peaks is not reflected in the data they collect.”
On the importance of mine safety: “My friends in the United Mineworkers of America are quick to remind me that the regulations of today are written in the blood of miners of the past. As our panel from the National Academies learned, knowing what we should do is not sufficient. We have to actually do it, and we need to remain vigilant.”

Silicon Dioxide is a natural compound of silicon and oxygen found mostly in sand, Silica has three main crystalline varieties: quartz, tridymite, and cristobalite. Fine particulate silica dust from quartz rock causes over a long-term progressive lung injury, silicosis.
Millions of U.S. workers are exposed to respirable crystalline silica in a variety of industries and occupations, including construction, sandblasting, and mining.
The new OSHA rule governing respirable crystalline silica calls for medical surveillance screenings to allow for identification of silica exposure-related health effects in certain workers.
Background. The practice of fracturing reservoir rock in the United States as a method to increase the flow of oil and gas from wells has a relatively long history and can be traced back to 1858 in Fredonia, New York, when a gas well situated in shale of the Marcellus Formation was successfully fractured using black powder as a blasting agent.
The Texas Silica material is a white or tan sand, or ground sand. ... Wear protective equipment specified below. ... The method of exposure to crystalline silica that ...
Evolution of Blast Furnace Iron Making. The origin of the first smelting of iron is concealed in the unrecorded history of human civilization. The first evidence of iron implements being used in ancient times actually comes from Egypt where an iron tool was found in a joint between two stones in a pyramid.
When we refer to hazards in relation to occupational safety and health the most commonly used definition is 'A Hazard is a potential source of harm or adverse health effect on a person or persons'.
The Occupational Safety and Health Administration (OSHA) is amending its existing standards for occupational exposure to respirable crystalline silica. OSHA has determined that employees exposed to respirable crystalline silica at the previous permissible exposure limits face a significant risk...

The Mill Process
1936. BCMM# 13484
Prior to the stock market crash in October 1929, the Mill at Britannia produced peak volumes of chalcopyrite (the major ore of copper) and wealth for both the British Columbian and Canadian economies.During this period, the Mill was processing up to 6500 tons (14,000,000 pounds) of rock daily. That’s as much weight as 480 elephants every day!
The main function of the Mill was to separate the waste rock from the minerals (mainly chalcopyrite) that the mining company wanted to sell. All the ore was ground up to the consistency of flour and put through a chemical process known as froth flotation, which causes the valuable minerals to rise to the top and the waste rock to fall to the bottom.
The ore at Britannia Beach was rich in copper. It contained an average of 1.25% copper or 25 pounds of copper for every ton of ore. After the ore went through the Mill, the end product was 26% copper, or 520 pounds per ton. This was very efficient. Britannia’s froth flotation process was so widely used that it became known as the Britannia deep cell method.
The more ore that was processed the more money the mine made. To maximize profits, the methods of separation within the Mill were constantly being updated and improved. Every year the process would change slightly to yield greater amounts of ore. The Britannia Mines Mill earned a reputation as one of the most productive mills in the world.

Right now, the iron ore price is US$109.50 per ton after a 2.8% gain overnight. As per the Trading Economics data, there is a boost of 23.7% over the past month. And this has lifted the fortunes of many ASX mining shares, especially the iron ore pure play Fortescue Metal Group Limited.
The Fortescue prices hike up to 25.4%, and ASX iron ore shares hike up to 21%. And creating this new share price flexibility, China is easing the restriction under the COVID ZERO POLICY.
This means that some manufacturers will be able to resume work, and therefore the demand is increasing for iron ore. Australian exports have also increased this year due to high Iron Ore Importers, and partially because the Brazilian declined exports.
Brazil is the chief competitor in the global iron ore supply. But the Vale Mine Disaster in 2019, impacts production in the country and meant more market share to Australia.
Iron ore pricing in 2022
The price of iron ore fell from a peak of about US $160 per ton in march of 2022. The big reason for this fall was the Covid-zero policy by China. This shut down many industries for a long time during the 2022 time period. Lockdown is the main reason for the fall in iron ore prices.
Although, things are getting back to normal as the protest against the lockdown argued the government of China to ease some rules and relax a bit. But it is a bit too early to expect the iron ore pricing will fly high.
How much the iron ore be worth in 2023?
ING expects the price of iron ore to slide to 62%, which is US $85 per ton in the first quarter of 2023. A slight improvement is also expected of about US $90 per ton throughout the second and third quarters of the year. The estimated expectations are based upon the further ease of the COVID restrictions by China. The price of iron ore can also reach above US $90 per ton in the final quarter of the year.
Why the expectation by ING is low for iron ore price?
There are a few factors on the demand and supply sides of the equation that will likely reduce the price of iron ore in the year 2023. On the supply side, the three biggest miners in Australia built new mines in recent years and are ramping up the production of iron ore.
BHP’s 80 mtpa South Flank mine began its operation in 2021 and is the largest among others. There are other mines, including Rio’s 43 mtpa Gudai Darri mine, which started its operation in June 2022, and Fortescue’s 30 mtpa Eliwana mine, which was started in 2020.
And on the demand side, China continues to cap crude steel output and looks to replace the older steel capacity with the electric arc furnace capacity, including as a part of the decarbonization plans.
China’s Covid Zero policy plays a vital role in the fall of iron ore pricing, and the ease of restriction in the policy helps iron ore to reclaim its position. But as per the report and prediction, it is safe to say that the iron ore prices will hike in 2023 and will be stable at the end of the year if the situation stays the same as now and all the production, supply, and demand factors works with each other as the bond.

Specification Stone Products operates two Michigan quarries – the Onaway quarry and the Alpena quarry. The Onaway quarry was started in the 1940s. The stone from this quarry was highly sought after due to its excellent design properties. In fact, the local post office was made with stone from this quarry. The Glawe family had been involved in the forestry and lumber business and had previously worked with Wallace Stone in sorting Rip Rap. This Rip Rap has been used for all the marinas around the area. The family purchased the Onaway quarry and, later, the Alpena operations.The Alpena quarry was purchased in 1987 from Straights Aggregates, which was owned by the Detroit and Mackinaw Railroad. They started the quarry in 1980. In 2009, both the Onaway and Alpena operations were purchased by the Levy Group of Companies.
The stone from these quarries has been used for many interesting and beautiful applications including:
High school and elementary students bring awareness to the amazing geology of northeast Michigan.

China may rule the increasingly ravenous world market for rare metals used to make smartphones, clean-energy technology, guided missiles and bombs.
But Colorado and other Western states also contain significant caches of rare metals – the makings of a modern-day gold rush. Mining companies, the federal government and state agencies are pushing to find out just how much potential new money lies beneath the dirt.
The exploratory work is intensifying because, after undercutting global prices for rare earths in the 1990s, China now mines 97 percent of the world supply. Past mining operations left Colorado with 7,300 abandoned projects that still leak toxic waste into soil and water.

Impact crusher and hammer crusher are both mining equipment, mainly for crushing stones of different sizes to provide the required materials for various infrastructure projects, but which is better, hammer crusher or impact crusher? Which has the highest output? What is the difference between the two? Many customers have questions about this. This article will introduce the two types of crusher in detail from three aspects: structure, raw material and output.
There are differences in the structure of impact crushers and hammer crushers. The impact crusher has a larger crushing chamber and feed opening compared to the hammer crusher. When the material enters the impact crushing chamber through the feed opening, the material is not only impacted by the hammer head, but also by the the impact plate, so the crushing is more adequate and the production of large pieces of material can be better achieved. In comparison, the hammer crusher has a smaller crushing chamber, and the hammer crusher is better sealed than the impact crusher, less dust pollution produced, so the hammer crusher has the advantage of being environmentally friendly.
2. Raw Material
The impact crusher is suitable for soft materials with feed size≤800mm and high compressive strength up to 350MPa, such as limestone, coal gangue, concrete, etc. The gap between the impact plate and the hammer can be easily adjusted to effectively control the discharge size.
The hammer crusher is suitable for medium hardness and brittle materials with feed size≤1200mm and compressive strength below 200MPa, such as lime stone, dolomite, slag, coke, coal, etc. It is especially suitable for highway, construction and large project materials.
The impact crusher, with an output of 30-800t/h, is also capable of meeting the needs of large sand and gravel plants, and can also be equipped with two or three units, with low initial investment costs, plus an optimised cavity design, compact structure, strong machine rigidity and a rotor with large rotational inertia to improve work efficiency.
The hammer crusher has an output of 80-3000t/h, which is relatively large. It achieves one crushing and shaping without the secondary crushing process, with high production efficiency, and by changing the cavity type, it can realize the conversion of coarse, medium and fine crushing, which greatly reduces the cost.


Buhari presented with gold bars mined in Zamfara as Nigerian prepares to launch PAGMI scheme.
The gold is expected to become a part of Nigeria’s external reserve after being purchased by the CBN.
The Governor of Zamfara State, Dr. Bello Matawalle, was at the State House in Abuja to present gold bars mined in the state to President Muhammadu Buhari.
A media aide to the President Buhari, Bashir Ahmad, announced this in a social media statement on Tuesday.

This comes as the Presidential Artisanal Gold Mining Development Initiative (PAGMI) is set to boost artisanal gold mining in the state.
Nairametrics reported that Nigeria had earlier mined, processed, and refined gold under the Presidential Artisanal Gold Mining Development Initiative, PAGMI. The first batch of PAGMI gold was unveiled at a presentation ceremony to President Buhari on July 16, 2020.
The Honourable Minister of Mines and Steel Development, Olamilekan Adegbite, said the gold produced is expected to become a part of Nigeria’s external reserve after being purchased by the Central Bank.
“PAGMI will result in the creation of thousands of new mining and formalized jobs, leading to poverty alleviation for many households. Under the scheme, artisanal and small scale gold miners will earn more from higher productivity, better recovery rates through mechanization of operations, and better access to reliable geological information,” he said.
The Minister also told reporters in July that the government is working with a Canadian company to begin the export of Gold in Nigeria’s proven one million ounces of gold by next year, adding that data would have to be collected on the minerals Nigeria has in large quantities through an Aero Magnetic Survey, which is done through a plane flying low to observe mineral data.
Nigeria’s proven surveys have discovered large quantities of gold in Zamfara, Kebbi, Niger, Kaduna, Osun, Kwara, and the FCT.
The minister says Nigeria’s proven gold reserves could rise to over 200 million ounces and Nigeria plans to begin processing of local minerals next year.

Over the past weeks, gold stocks have been riding on rising gold prices as the coronavirus pandemic and growing concerns of a recession push investors to the precious metal. However, on Tuesday gold gains were halted after rising 1% on Monday as the dollar became strong. But the bullion losses were limited by the current volatile equity markets.
On Monday the plunge of US oil prices increased gold’s appeal but going to Tuesday spot gold fell 0.2% to $1,689.45/oz. On the other hand, US gold futures eased 0.4% to $1,704.60/oz.
Gold Stocks Benefiting From High Gold Prices #1 Newmont Corporation
The coronavirus pandemic has hit several sectors including mining but with several operators reopening mining this could boost gold stocks. For instance, Newmont Corporation (NYSE:NEM) has indicated that it will reopen its gold mines in South America and Canada that it closed last month to combat the spread of coronavirus.

Roll crusher, appeared in 1806, is the most ancient crusher (jaw crusher), which is invented by English as man thomas. Its roots can go back to the ancient treadmill, which is the prototype of roll crusher. The working principle of treadmill is also the working principle of roll crusher. The treadmill continues to improve current in production process, evolving to several types, such as the plain-roll crusher, which is used in the metal mine industry; the rod-toothed crusher, which is used in the coal industry and so on. However, the development of traditional roll crusher is limited, making slow progress. In the 1980s, based on research result of professor shaw in university krauss, krupp company and khd company in german launched the high-pressure roll crusher. The high-pressure roll crusher adopts the high-pressure crushing force, which devastated the material in the contact.
The impact in the roller reduces the relative sliding action between the material and the roll surface. The high-pressure force from roll to the material surface improves the working efficiency of crusher and reduces the wear rate of roll surface, making the high pressure grinding roller move towards the industrialization. The machinery manufacturing methods of Hongxing roll crusher and rod-teethed crusher has always been a mystery in machinery manufacturing industry. By the same author: Peter Thiel. Hongxing roll crusher has been awarded three national patents. Now, let Hongxing experts share their technology with us patent. Unique roll crusher structure First of all, driving system works like this: two motors drive rollers through triangle belt transmission. The two rolls force the ore particles between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.
Secondly, the coexistence out of the equipment can be adjusted. The particles are drawn into the gap between the rolls by their rotating motion, to wedge block formed between the rolls and the particle, called adjusting device. Adjustment bolts are fixed on the top of the wedge block. When bolts pull wedge block up, the wedge block push moving away from fixed roll roll, the gap become bigger, and the discharging coexistence become bigger. And vice versa. Double roll crusher have teeth on the face of the roll, and it is designed with high capacity. The connecting method about motor and speed reducer adopts hydraulic coupler. The equipment is mounted with overloading protective device to ensure operation. The gap width between the rolls can be changed by hydraulic adjustment system. Centralized lubrication system, which can lubricate all parts. Tooth design optimized. With economic growing a variety of metals and non-metallic minerals, cement factories, buildings, gravel and metallurgical industry have expanded their production scale; crushers their processing machines play a very important role in the development, and have become stanchion of the industry. It is expected that efficient free-pollution fuel and machinery will have good development prospects in the future. To a certain extent, reducing power consumption or improving system output can solve the problems of low production and disorder operation in cement enterprises. Roll crusher continually accelerate its development, adopt a simple, practical and versatile mechanical electrical protection system for hydraulic crushing materials of medium hardness in cement, metallurgy, chemicals, electricity, coal and other industry sectors, for example, it is used in coarse crushing or fine crushing limestone, slag, coke, coal and other materials.

In a coal based captive thermal power plant, coal is received from coal blocks/Mines by means of railcars or barges. Then the Coal is dropped in a coal yard and usually stored in stockpiles. Reclaiming of coal from stockpile is done using an automatic reclaimer/stacker consisting of reclaim tunnel hoppers and feeders. After that Coal is conveyed to the crusher house for coal crushing and transferred to belt feeders from where it is fed to the boiler.
Although many handling issues encountered in bulk storage but in case of coal storage or lignite storage, followings are the major handling issues to be faced while operating the boiler:
- The most common problem in operating coal under coal storage sheds is flow blockage. It largely depends upon bulk density, particle size and moisture content in the coal.
- Sometimes while handling, coal remains stagnant outside the feeding channel which has the tendency to combust spontaneously. Such Stagnant material may pose threat to fire.
- When material discharge from conveyor belt to the chutes for a long time, the friction of material with chute surface increases and thereby reduces the velocity of steam coming from the boiler.
- Boiler efficiency is mainly depended on presence of fuel properties in coal like hydrogen, moisture, and various other fire supporting elements in coal. To sustain excellent boiler efficiency, we have to keep losses (due to absence of such fuel properties in coal) to their minimum extent.
- Few other factors responsible for sustaining maximum boiler efficiency are ‘keeping optimal air level’, ‘keeping the fineness of coal to required level’, ‘proper rotation of coal in power plant to avoid combustion’ and more.
