### Dioxazine Crude Grinding By Ball Mill

The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill.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.
