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, density, temperature and …

The balls become coated and the grinding efficiency decreases. The pilot mill is also equipped with a sensor measuring the 'ball and pulp toe and shoulder angles' (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite

In order to in-depth study of the influence of alumina grinding balls on the subsequent flotation indexes after the regrind of the copper concentrate, after the test and comparison mills have been running stably for 3 to 5 days, the subsequent selection indexes were carried out for 10 days in each period for 20 days. According to the ...

Ball mill grinding efficiency is influenced by many factors: ore grindability, feed size, grinding product size, ball mill diameter and length, ball mill working speed, liner type, steel ball loading system, grinding concentration, return sand ratio in closed-circuit grinding and feed rate. (Ball mill) To improve the ball mill grinding efficiency, you must first understand the …

A method of grinding a mineral-containing ore, which includes grinding the mineral-containing ore in a primary milling process and thereafter fine grinding the mineral-containing ore in a secondary ball-mill. A composite grinding medium comprising a mixture of steel balls and pebbles is used in the secondary ball-mill. The pebbles have an average size which is …
