There are many different kinds of mine-selecting equipment, like classifier, magnetic separator, shaking table, construction chute, high frequency screen, flotation machine and so on. Ball mill is one of the important ore-dressing equipments, so selecting a suitable ball mill is a critical thing. There are some methods for choosing it.

1. Reducer device: improve speed is the effective rule to raise the efficiency of energy-saving ball mill’s operation; the fast speed is helpful for high efficiency. Therefore, appropriate improvement to reducer device can play a certain effect, yield will increase naturally. The affluent plant can also install the frequency converter to adjust the revolving speed and achieve satisfactory results.

2. Ball mill liner: mill liner is used to protect the cylinder, avoiding the direct impact and friction of grinding body and material to the cylinder, different types of liners can adjust the state of motion of grinding body in every chamber, in order to achieve the best grinding results.

3. Ball choice: pay attention to the importance match of ball diameter, ensure different sizes of steel ball’s diameter so that you can fully grind the ore of different sizes in cavity, improving the working efficiency of the ball mill.

4. Electrical appliances: For energy-saving ball mill, increasing the current in order to improve the speed, high speed can enhance the efficiency naturally. According to the tonnage of the loading capacity of the grinding body, you can roughly determine how much power should be equipped with motor. But here to note that increase the current must not exceed the rated power range of the ball mill, not exceed the maximum load, if the current is too large, it will burn the mill motor, the loss also increases.

5. Added water amount: ore moisture has a certain impact on the efficiency of the energy-saving ball mill, therefore, increase appropriate moisture of mill cavity can serve it and increase ball mill's efficiency. The traditional regular maintenance cannot be scientifically predict the failure, so it cannot fundamentally prevent failure of the ball mill, which will increase maintenance costs and repairing time, also the maintenance cycle is too short, resulting in waste and affecting the normal use. Therefore, you require doing the condition monitoring and fault diagnosis of the ball mill gear transmission system to analyze the operational status and performance of the ball mill gear transmission degradation trend, determining the need for maintenance depending on the specific situation, so that you can not only be effective in preventing the occurrence of the fault, but also can reduce unnecessary maintenance savings.
