1, the grinding media shape and material: as a grinding medium directly produces a ground effect on material, it should satisfy and meet the requirement of two aspects: one is the largest possible surface area, to provide the appropriate surface with grinding materials in contact with quality; two is as large as possible, in order to the ground material needed energy.

2, the grinding media size and proportion: the size of grinding media size in relation to their impact, the material in the ball mill grinding extrusion and the role of the strength, directly affect the grinding effect. In determining the size of the media, the main consideration is the nature and size of grinding ore composition.

In 3, the amount of the grinding media: when the diameter, length and speed of ball mill rate, in the range of not more than 50% ball loading rate, increase the useful power of ball mill with ball loading rate increases, production capacity will increase. But different speed have different limit ball loading rate, on the critical speed within the operation, ball mill ball load rate is usually 40% to 50%.

4, reasonable adding grinding medium: the grinding medium in the process of grinding material, its also unceasingly to wear, in order to make the ball mill to maintain different size medium has a proper proportion in the grinding process, and the medium the rate constant, must fill the new medium with a certain size and number of every day to compensate for the ball mill, wear out of medium quality.
