Effect of grinding media steel ball on grinding efficiency of ball mill Dec 04, 2018

In actual production, the grinding media steel ball used will directly determine the grinding efficiency of the beneficiation ball mill. As is known to all, in order to ensure the quality of production, the grinding media steel ball used in the beneficiation ball mill has strict requirements on the quality. It is often necessary to estimate the wear of the steel ball in the mill, and add a certain amount of steel ball to the beneficiation ball mill at an appropriate time.

It should be noted that the humidity of the ore material entering the beneficiation mill should be controlled in actual production, because if the humidity is large, the static electricity generated by the ore material is stronger. In this way, the ore material will accumulate under the adsorption of static electricity, and will adhere to the steel ball and the liner under the impact of the grinding medium steel ball to form a buffer layer. This in turn leads to a decrease in the grinding efficiency of the beneficiation mill.

For the user, when selecting a beneficiation ball mill to grind a media steel ball, two problems should be considered: first, the steel ball selected is not as hard as possible, but the proper hardness value is to be ensured. In this way, the quality and output of the product can be guaranteed at the same time in actual use.

The second thing to note is the density of the grinding media steel ball, which is also an important factor that cannot be ignored. This is because the operation of the beneficiation ball mill is in a state of constant change. If the density of the steel ball is not ideal, it will also result in inefficient grinding of the beneficiation mill. Of course, it also includes some other factors, such as the mill gear during the beneficiation process is also an important factor affecting the grinding efficiency.

In summary, in order to ensure the efficiency of the beneficiation operation, the user should reasonably select the grinding media steel ball. On the one hand, it is necessary to ensure that the hardness of the grinding media steel ball is suitable, on the other hand, it is necessary to ensure that the density is suitable.
