2020-4-11The ball mill ball ratio should be judged according to the effective length of the mill, whether it is equipped with roller press, feed size, lining material and structure, and the number of rotation speed. After installing the ball mill, ball mill size gears need to be meshed and the amount of processing is also gradually increasing.

2017-1-3Ball mill power draw predicted from the Denver slide rule, kW 0 200 400 600 Calculated ball-mill power draw from the m odel derived, kW Data compared Line yx Fig. 2. Comparison of the ball mill power draw from the Denver slide rule and the proposed model. Dashed line corresponds to yx.

The measurement of the ball charge volume load or filling degree is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill vertical distance between the top of the charge and the lining in the mill axis.
