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 ...
