Introduction. This article concerns itself with vertical grinding mills used for coal pulverization only (coal pulverizers), although vertical grinding mills can -and are- used for other purposes.. The 3D model in the saVRee database represents a vertical grinding bowl mill.Other grinding mill types include the ball tube mill, hammer mill, ball and race mill, and , roll and ring mill.

Vertical Mills comprise 2-4 conical rollers which are hydraulically pressed onto a horizontal rotating grinding table. Material is directed onto the centre of the table and is thrown outward by rotation under the rollers. Fines pass out with the air current while coarse material falls back onto the feed table. A major cause of material instability is fine, dry mill feed which can usually, be
