Hammermills versus roller mills
Roller mills particularly single pass installations require more care and attention than hammermills in order to achieve a consistent and accurate grind. Ensuring the feed is spread thinly across the face of the roller mills can present some problems as mechanical feed gates can easily become obstructed impairing the smooth and regular flow.

VRM Presentation Mill Grinding Cement
Vertical Mills comprise 24 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.
