Standard operation of ball mill

Ball mills are a very common type of grinding equipment only in beneficiation applications. The grinding principle is to use the friction between the material and the steel ball or the steel column and the rotating form of the drum to promote the material to reach the ideal particle size standard, so as to facilitate the classification and flotation in the subsequent beneficiation process.

All mine
There are two main meanings: First, the composition of the ore particle size is uniform; In order to improve the grinding efficiency, the amount of ore feeding should be continuous, uniform and stable at a high level.

Big return sand
By studying the relationship between the sand return ratio and the relative productivity of the mill. It can be known that within a certain range (such as between 100% and 500%) as the sand return ratio increases, the productivity of the mill increases with the increase. When it reaches a certain value, the productivity increase is very small, and the full feeding of the mill is close to the maximum. Through the ability, it is easy to cause the ball to distend the belly. Therefore, the sand return ratio should be kept stable, close to a constant value.

High concentration
In the operation of the grinding machine, a higher grinding mass fraction is generally used, so that a layer of pulp can be attached to the surface of the medium, thereby enhancing the grinding effect favorable for grinding. Therefore, “high concentration” refers to appropriately increasing the grinding mass fraction within a certain range, which is beneficial to improve the grinding effect.
