In order to use coal more rationally, efficiently and effectively, the coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove, 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm. So coal processing in coal preparation plant includes coal crushing and coal milling. Coal crusher consists of many types of crushers and grinding mills. Coal crushers including jaw crusher, impact crusher, cone crusher etc. Coal mill include ball mill, vertical mill, raymond mill etc. SBM is a coal mining machine manufacturer in China, located in Shanghai. It supplies all kinds crushing machines and design stone crushing production line according to the requirements of customers, such as aggregate rock crushing plant, iron ore crushing plant, coal crushing plant ang grinding plant for sale with best price. The particle size of slack coal is 0 ~25 mm. Theslack coal is often used as combustion agent in steel company, thermalpower plant, etc. The consumption of coal is quite large in thermalpower plants. Take a 1 million kW thermal power plant for example, coalconsumption amounts to 11, 000- 13000t a day, which takes 60% ~ 80% ofthe cost for generating electricity. It is advisable to adoptappropriate coal mill for coal grinding. This can not only improve theutilization of coal, but also contribute to energy saving, environmental protection, economic benefits. According to the market research, vertical coal mill is used most widely. There are also other grinding mills like traditional Raymond mill, roller mill, trapezium mill, etc. can also meet different requirementsfor grinding coal into different sizes and types. Customers can choosean appropriate coal according to their specific needs.As coal powder is the most important fuel in the power plant, Theplant owners need coal mill or coal pulverize to grind the coal tomicro powders. Raw coal (crushed) is fed through hopper at the top of the coalpulverizer and falls down to grinder ring to be pressed, crushed andmilled into pieces by rollers. After the first crush, coal powder fallinto the second and third layer. The pumping of the high-pressurecentrifugal blower put the outside air into the coal mill. The coarsecoal powder will be brought into the classifier. As a pioneer in coal pulverizer, Shibang has positioned itself well to meetthe challenge of supplying coal mill with reliably quality andefficiently at the lowest cost. SBM 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 powerplants. The power plant can equipment different kinds coal mill to meetthe required size. Coal processing plant is a broader term used to describe the complete process of sizing, handling and washing of the run-of-mine coal. Clean coal technology is a series of newly developed coal processing, conversion and combustion of soot in the flue gas channel of the general purification technology. Aim is to reduce the pollution of coal burning on the environment, improve coal utilization efficiency, and lower costs. Clean coal technologies can be divided into three categories. Before burning through coal preparation or admixture of other substances to improve combustion efficiency and pollutant removal; combustion, combustion and the nature of change in the combustion process to remove contaminants; combustion, flue gas decontamination. Coal preparation serves several purposes. One important purpose is to increase the heating value of the coal by mechanical removal of impurities. This is often required in order to find a market for the product. Run-of-mine coal from a modern mine may incorporate as much as 60 percent reject materials.
