Ball mill equipment is the necessary equipment for grinding operation in concentrator. It is not only the equipment for crushing after crushing, but also the basic operation of concentrator.
Ball mill Whether the equipment is purchased or not directly affects the grinding efficiency and indirectly affects the overall concentrator efficiency. What details should be paid attention to when choosing the ball mill?
1. Selection of ball mill type
When purchasing ball mill, it is suggested to select ball mill equipment according to the actual production conditions and the materials (to determine the material, hardness and grade) of the concentrator.
2. Selection of ball mill model
According to incomplete statistics, there are about 34 types of ball mills, and the length, width and height of each type of ball mill, cylinder speed, ball loading, feed and discharge particle size, output and so on are different. Generally, when the feed particle size is ≤ 20 - ≤ 25mm, the processing capacity is 0.65-615t/h, the motor power is 18.5-4500kw, and the processing particle size is about 0.075-0.4mm. How to choose should be selected according to the needs of the concentrator Suitable model.
3. Grinding test auxiliary
When there is no actual data as the basis in the design of concentrator, it is necessary to make grinding test. Especially for large-scale concentrator, the mill selection calculation and scale-up should be carried out from the obtained basic data. Through the test results, the ball mill equipment with high operation rate should be selected.
