Hammer mills and ring crusher mills are types of crushers that utilize attrition as the major means of reducing the coal size. Crushers like these (Figures 32 and 33) employ the centrifugal force of swinging hammers or rings striking the coal and then scrubbing the particles between the hammers or rings at the discharge grate bars.

The BTM is a lowspeed mill that primarily grinds coal by impact and attrition. The VRM is a medium speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed

20. Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...
