13.1.1.2 Medium-speed mill. Medium-speed mills are smaller than low-speed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75–225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.

The exhauster supplies pulverized coal to three riffle type distributors. The riffle distri- bution system on each mill supplies pulverized coal to eight coal nozzles, a total of 32 coal nozzles for the entire boiler. The exhauster discharge pressure is approximately 10 to 12" w.c. under full load operation.
