## A New Approach to the Calculation of Work Index and

The mill dimensions, (D × L), are 0.204 × 0.3 m and it is loaded with 8.55 kg steel rods 14 to 20 mm diameter. The mill rotates on rolls and its frequency is set to 70 RPM corresponding to 85% of the critical frequency. The mill power is = 22.5 Watts, calculated by (6).

## Mill Speed - Critical Speed - Paul O. Abbe

Calculating how fast a Jar needs to spin is a little tricky, but simple one you know the factors. We need to know the inside diameter of the mill, that determine what speed we want, the outside diameter of the mill and the diameter of the rollers. The last two diameters will tell us how fast the roller has to spin to achieve our Jar speed.SIZE REDUCTION AND SIZE SEPARATION,At this speed the balls are carried almost to the top of the mill and then fall in a cascade across the diameter of the mill. By this means the maximum size reduction is obtained by impact of the particles between the balls and by attrition between the balls. Generally it is 0.5 cycles per seconds (cps).Hammermills versus roller mills | World Grain,Hammermills versus roller mills,the roller mill can be used quite effectively and can be a key part of reducing power consumption at the mill.,
