According to the production practice of production enterprises, the relationship between vertical roller mill diameter and material size is shown in Table 1-11.
A kind of Steel vertical roller mills are gradually worn out in the process of grinding materials. The wear of drop steel vertical roller mill is related to its impact force. The wear of grinding steel vertical roller mills is related to the surface area of steel vertical roller mills.
In general, the steel vertical roller mill in the grinder has both impact and abrasion effects, so the wear is proportional to the n power of the diameter of the steel vertical roller mill, and the value of n is between 2 and 3.
The quality and surface area of forged steel vertical roller mills of various sizes are shown in Table 1-12. A kind of Because of the wear of steel vertical roller mills in the mill production process, in order to keep the mill stable. Steel vertical roller mills need to be added regularly.
