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

calculation for vertical roller mills. nozzle ring velocity calculation in vertical roller mill INTRODUCTION The vertical roller mill is the appropriate equipment for Reducing the gas speed in the nozzle ring (adjustment of the open area) The required gas flow rate through the mill has to be calculated e.g. through a heat balance.

Oct 05, 2016 Better product quality can be achieved as compared to the ball mill product due to the better options for separate grinding. For example, in additive cement production, the blast furnace slag has to be ground to Blaine values of 5,000 cm 2 /g. Water demand and setting times are similar to that of a ball mill cement under comparable conditions .
