The vertical roller mill is one of the most important ore beneficiation machines in the mining industry. There are many reasons influencing the grinding fineness of the vertical roller mill. Here our experts will give you some helpful advice to control the grinding fineness of the vertical roller mill.

The abrasion degree of the vertical roller mill blades is a core problem we need to care about. When the blades are worn, few materials will be fed back which will cause the grinding fineness to become larger. The size of the vertical roller mills discharge hole plays an important role in the ore beneficiation process. The bigger the size is, the larger the material feeding amount gets and the finer the grinding materials will become.

In the actual production process, we can do reasonable arrangement of all kinds of minerals in order to guarantee the uniform size of the minerals and the well distribution of the ore powder and bulks. Its also a key step to adjust the particle size of the crushed materials and change the size of the screen grid holes. If there are changes of the particle size of the materials happening during the production, we must report this situation and adjust the grinding fineness to make it smaller.

We should also pay attention to the rotary speed of the vertical roller mill. Before and during the operation of the vertical roller mill and classifier, we should adjust the rotary speed to the proper one in order to guarantee the excellent performance of the mining machines.
