Description

After choosing the maximum diameter and minimum diameter of steel balls according to technological requirements, material properties, vertical roller mill specifications and various parameters, and then matching grade, using curves, the accumulative percentage of the mass of each corresponding steel balls loaded into the vertical roller mill can be found, the actual percentage of the mass can be calculated, and the loading quality of steel balls at all levels can be obtained.

According to the production practice of production enterprises, the relationship between ball diameter and material size is shown.
