Mediumspeed mill. Mediumspeed mills are smaller than lowspeed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.

The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be % ~ %, while that of raw coal is % ~ %. Therefore, the ball mill should have a drying function besides grinding.

The coal mill is a vertical roller mill, in which the coal particles are collected in a bag filter through a grit separator. The required size of coal is 80% of 90 μm and less than 2% of 212 μm (Atmaca and Yumrutaş, 2014). Hot air generated in a coalfired furnace or from a cooler/preheater is used for drying the coal in the mill. The ...

VRM's are fed either with a rotary feeder or a flapgate system. In either, the primary role is to provide an airlock function to minimize the introduction of "false air" into the mill and separator. Excessive false air has negative consequences: The ID fan must be larger; therefore, more costly to acquire and operate.
