Coal Grinding Mill is an important coal powder furnace auxiliary equipment. Coal grinding process is the surface area of the coal is crushed and its growing process. To add a new surface, molecules must overcome the adhesion between the solid, which consumes energy.
Coal mill is an important auxiliary equipment for coalpowder furnace, it has three methods to crush the coal lump and grind them into powder,it is crushing, impacting and grinding. Air swept coal mill is the main equipment in cement plant for both drying and grinding of the powders.
The situation is further complicated by the ''mill reject'' streams that reject undesirable material (tramp metal and noncoal bearing rock) from the mill. Generally, the following steps illustrate the path through a VSM: • The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table; •
