Six factors affecting the output of grinding mill DC Velocity
The particle size range of the grinding mill is wide, and the particle size can reach 2500 mesh. 2. Hardness of grinding materials. The harder the material is, the more difficult it is for the grinding mill to grind, and the more severe the wear of the equipment is. Raymond grinding speed is slow, of course, Raymond grinding capacity is small.Ball Mill Parameter Selection & Calculation JXSC Machine,1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, Feed Size VS Ball Size Grinding & Classification Circuits,For ball mill, Bond (1958) was proposing an empirical formula giving the top size of balls (makeup balls) DM function of the feed size xG (80% passing size µm), the ore true specific gravity sg, the ore Bond Work Index Wi (kWh/st), the fraction of critical speed fc and the inside mill diameter D (m):
