Coal Mill Is the Ideal Equipment for Coal Processing

Coal mill is major equipment of cement plant and used for drying and grinding coal. The equipment is mainly consisted of feed device, main bearings, rotating parts, drive device, selling device, high-voltage start-up device and lubrication system. The raw material is fed into mill by feeding equipment. The hot wind enters into the mill by inlet end. As the mill cylinder rotates, the coal and hot air exchange heat in the mill. The coal is crushed and grinded in the mill.   The coal mill we make is with reasonable structure, high grinding efficiency and is the ideal equipment for coal processing. In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles. The primary air flow to the furnace is fed through the mill, with the purpose of heating and lift the coal particles out of the mill and into the furnace. If the the particles are too heavy they will drop to the bottom of the mill and will be pulverized once more. The coal particles are heated to 100 degrees Celsius. The temperature of the primary air flow is manipulated for controlling this temperature measured as a temperature in the mill at the exit. The primary air temperature is controlled by controlling the position of an air mixer, which mixes heated outside air and cold outside air.Scientific management, advanced processing technology and innovative manufacturing theory make Fote Heavy Machinery become the exporting base of raymond mill, powder grinding mill and famous grinding equipment in China. What Hongxing has done is for the clients and we believe that quality is the best way to develop market. In order to control the energy production of the plant, the coal flow into the furnace is an very important factor. Unfortunately, it is...
