Vertical mill calculations Power consumption The theoretical power consumption of a vertical roller mill is expressed by the formula: N = KT A z v p [kW(net)] For the vertical mill the following applies: KT: Typically 500 700 A = Droller W roller Droller =0.6-Do W roller = 0.2 DO Do = Mill size/10 z=3 v = n 1/60 Dm TT Dm =0.8-Do [kN/m ] [m

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill “sees” instantaneously unless some damping system such as a surge hopper is used.
