Coal pulverizers and cement vertical roller mills operate in very similar ways. A table with large sized raw material rotates, while stationary grinding wheels roll over the material to grind it into finer particles. The wheel in these applications typically has a spherical roller bearing to take thrust loads and a cylindrical bearing to take

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% ...
