A Comparison of Three Types of Coal Pulverizers
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 decreases with mill size and remains constant for a given mill diameter.

We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thouh of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength. The Wonder Cement factory process is now complete.
