Coal is the important energy resources and mineral resources in our life. In order to use coal efficiently, we usually crush coal into powder by coal crusher.
Coal jaw crusher is the most common crusher equipment in coal crusher plant and used as primary coal crusher. It can crush big coal into small pieces. impact crusher is another common crusher that is used in coal crushing process. It is mainly used in primary or secondary crushing process. cone crusher is used as fine coal crusher machine, and used in secondary or tertiary crushing process. hammer crusher is a coal crusher with small capacity. Usually it is used with coal mill to grind coal into powder. Mobile coal crusher is the convenient coal crusher. It unite the crushing equipment, belt conveyor , and vibrating screen . So crushing and screening process can be finished in this machine.
These stone crushers have their own benefits. How to choose which type of coal crusher is used in coal crushing depends on your requirements, such as crushing capacity, the finished size, etc.
The Coal classes
Coal is divided into four classes: lignite, subbituminous coal, bituminous, and anthracite. Of the commonly minable coals, anthracite is the hardest and has the most carbon, giving it a higher heat value.
Coal crusher used in coal processing company
Coal processing is as follows: After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. During this coal processing, the used industrial equipment can be called coal processing equipments.
Meet the requirements of coal particle size selected. Featured the coal crusher can handle a certain size range, over the range of large to go through a break before washing. Coal jaw crusher is used widely as a efficient coal crusher and applied in coal processing company.
In the coal crushing plant , coal crushing can resize the coal stone so that it can be easily handled and processed. For the Mosh hardness of coal is usually under 5, the miners can use jaw crusher, JC jaw crusher, impact crusher, hammer crusher etc. to handle it. After the coal has been crushed, we need vibrating screen to grade the coal by size and then transport the coal via belt conveyor. In this process, dewatering screen is optional to remove water from the product.
Coal Crusher is acknowledged in coal processing industry for a long time. NFLG has many years manufacturing experience in coal crushing plant (coal crushing process, washing plant and belt conveyor). NFLG is a major coal crusher supplier for power plants and coke ovens, crushing limestone for blast furnaces, and crushing a wide range of raw and manufactured materials for industry.
As the largest exporter in the design and manufacture of coal crushers and spare parts, NFLG crushers are used in a wide variety of material reduction and processing applications in 100 countries around the world.
Some coal is a mixture of coal and waste rock symbiotic parting of coal, in order to choose the coal that needs to be broken into smaller particle size, separation of coal and waste rock. The most common case is to be elected in the primary election machine coal crushed to 13mm or 6mm following, and then sent to re-elect re-election machine.
Size to meet user requirements, the products or coal broken are after the election to a certain size. According to the product size broken, broken job can be divided into coarse pieces (the crushing to 50mm and above), in pieces (broken into 25-6mm), small and fragmented (broken into 6-1mm), crushed (1mm or less). So depending on the above parts, we need primary coal crusher, secondary coal crusher and tertiary coal crusher for different crushing.
Coal crusher applied for the station boiler
Station boiler is a boiler providing steam to the turbine generator in thermal power plant, including boiler and ancillary equipment. Fuel is burned in the boiler and releases heat energy, and heat transfer through the metal wall of the boiler water into a certain pressure and temperature of superheated steam, then steam into the turbine, the turbine-driven generators. Total thermal power generation capacity worldwide is about 70%, 80% in China. Therefore, the boiler and its role in terms of energy consumption or from the point of the development of the national economy have a significant influence. Most of station boilers’ fuel is coal, so coal crusher is the main crusher equipment in thermal power plant for crushing coal.
We should make optimal design of a coal crushing system. In order to promote the concept of coal particles and prefabricated, we use prefabricated, dry coal shed stacked, two broken and three screening can be a fundamental solution to block coal bunker coal, the furnace bed material quality degradation trends, improve coal preparation of system reliability. In this coal crushing process, NFLG coal crusher relies on its unique advantages in a wide range of applications in the station boiler system.
Coal mill:
As coal powder is the most important fuel in the power plant, The plant owners need coal mill or coal pulverizer to grind the coal to micro powders.
Raw coal (crushed) is fed through hopper at the top of the coal pulverizer and falls down to grinder ring to be pressed, crushed and milled into pieces by rollers. After the first crush, coal powder fall into the second and third layer. The pumping of the high-pressure centrifugal blower put the outside air into the coal mill. The coarse coal powder will be brought into the classifier. As a pioneer in coal pulverizer, NFLG has positioned itself well to meet the challenge of supplying coal mill with reliably quality and efficiently at the lowest cost.
NFLG can manufacture and supply coal mill for all grades from hard coal to coke coal, our ball mill , High pressure Raymond mill , MTW trapezium mill , MTM trapezium mill, Coarse powder mill and micro powder mill is an ideal choice for power plants. The power plant can equipment different kinds coal mill to meet the required size.
Coal mobile crusher for Opencast Coal Mine
With global scientific and technological progress, the coal industry is changing from labor-intensive into capital and technology-intensive. The coal technology has also transformed from mechanized production to automatic control. Robot or artificial intelligence combined with expert is the new way for coal mining.
In order to solve the problem of small coal mine area and inconvenient transport of equipments, NFLG, based on 20 years’ production experience and several years’ research, manufactures the world-class high-quality crawler type mobile crushing plant. It is made by impact crusher, jaw crusher, cone crusher, vertical impact crusher, conveyor, belt conveyor etc. It can meet different requirements “screening after crush” and “crush after screen”. The crushing process can be divided into two phases “coarse and fine”, and three phases “coarse, middle and fine”. Moreover the mobile crushing plant can operate independently and jointly with great flexibility.
Mobile crushing plant has changed the past old way of coal processing mode in coal industry. It improves the efficiency of integrative coal treatment and highly recommended in coal and mining industry.
Coal crusher plant
In fact, we rarely use only one crusher in coal crushing process. Usually we compose these coal crushers into a complete coal crusher plant.
A complete coal crusher plant includes crushing and screening machines. Jaw crusher is the primary crusher, impact crusher is the secondary crusher, cone crusher is the fine crusher. Raw coal is transported between these coal crushers through belt conveyor. The finished crushing coal materials is screened out by vibrating screen. The eligible coal materials enter into further process, while unqualified pieces return to the coal crusher for crushing again. In this coal crushing process, coal can be crushed into 30-50 mm. If you need coal powder, coal particle is grinded into powder by coal mill.
NFLG is a coal crusher supplier in China, and design coal crusher for coal crushing process. With the development of 30 yesrs, our products have formed two main kinds – crushers and grinding mills. Crushers include jaw crusher, impact crusher, cone crusher, and vsi crusher. Grinding mills include ball mill, raymond mill, vertical mill , and ultrafine mill. We also supply a complete crushing and screening plant, such as stone crushing plant, coal crushing plant, ore crushing plant, concrete crushing plant, construction waste crushing plant and ballast crushing and screening plant. Now our crusher machines have export to all over the world, such as Indonesia, Philipines, India, Vietnam, USA, Australia, South Africa, Egypt, Germany, Poland.
