The ball mill has a wide range of applications among so many mining machines and it is regarded as the highest working efficiency grinding equipment.

Today our experts will tell you the secret of the most efficient grinding machine, namely the importance of the ore grinding medium which will make difference to the ore beneficiation plants.

First, the shape and materials of the grinding medium plays an important role. As one grinding medium with the direct influence on the minerals, the medium should meet two requirements: large surface area which can provide enough touching area with the minerals; much weight which will provide enough energy for the grinding materials.

The particle size and the proportion of the grinding medium are also important factors for the ball mill. The particle size of the medium will have much effect on the ball mill’s impacting, pressing and grinding effects of minerals. Meanwhile we should also pay attention to the particle size and properties of the minerals that are to be ground.

Last, the charge weight of the grinding medium has also great effect on the working efficiency of the ball mill. When the diameter, length and the revolution of the ball mill are fixed, the charge weight of the materials should be controlled within 50% so that the ball mill’s available power will increase as well as the productivity. In addition, different revolution speeds will lead to different charging weight of the materials.

Knowing the basic information of the ball mill’s grinding medium will help users in the real operation of the ball mills.
