Ball Mill an overview ScienceDirect Topics
The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D
how to calculate volume in ball mill filling
how to calculate volume in ball mill filling [randpic] Mill Steel Charge Volume Calculation We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge vo
Frequency domain characterization of torque in
01/01/2018· There are two factors which make extremely difficult to correlate experimentally torque and filling level in a ball mill. One of them is a saturation effect appearing on torque as the mill filling increases. The other factor is the effect of the gears, always present to multiply the torque of the electric drive, which smear torque signal with non-related grinding components. In this paper, by means of
