EF5BM=[ P80+10.3 1.145×P80] ( 3 ) The EF4 formula requires both the rod mill and ball mill work index (rod mill Wi is used to calculate the optimal feed size) and because this is a "single-stage ball mill" calculation, the F80 is actually the rod mill feed size (10,000 µm) from Table 1 and the P80 is the ball mill circuit product. The EF5 factor only applies below 75 µm to ball

How full should a ball mill be? Generally, filling the mill by balls must not exceed 30–35% of its volume. A feature of ball mills is their high specific energy consumption; a mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, i.e. during grinding of material.

Calculator Use. Pressure is a scalar quality reflecting how force acts on a surface. P = F/A. Where P is equal to pressure, F is the normal force and A is area. Since pressure is derived from force and area, many units for pressure directly relate force to area. Some are obvious, such as pounds per square inch, but even the SI standard Pascal ...
