Equipment For Processing Coal Blocks Into Pulverized Coal

Last Update:2020-05-14 00:50:04

Which is the best equipment to process coal into pulverized coal? The vertical pulverizer is a rate equipment for grinding coal blocks. The particle characteristic pulverized coal is composed of powder with different size and irregular shape. The finished pulverized coal can be used in energy fuel of boiler, power plant, smelter and other industries, and can be used in cast iron process to improve the smoothness of castings.

How does the vertical mill grind the coal into pulverized coal with different fineness? The coal material falls to the grinding plate by the impact of gravity and air flow. The grinding disc rotates at a constant speed, and then the centrifugal force throws the crushed materials from the middle of the grinding disc to the edge of the grinding disc. The pulverized coal leaving the grinding disc encounters the hot gas entering the mill through the air ring, and then rises. The pulverized coal enters the separator through the shell in the middle of the mill. The materials that have not been crushed to the specified particle size are selected by the separator and sent back to the grinding disc for re grinding.

Vertical mill has a very good advantage in processing coal stone into coal powder. The vertical mill adopts a reasonable and reliable structure design, which integrates drying, grinding, powder separation and lifting together with the technological process. It is especially suitable for large-scale milling of various ores and grinding block, granular and powdery raw materials into the required powdery materials. Especially in the large-scale pulverized coal process, it can meet the needs of customers, and its main technical and economic indicators reach the international level. In the process of coal stone processing, it can ensure that the particle size of coal powder is uniform, the rate of passing sieve is high, and improve the production efficiency of coal powder.
