Scope

This standard specifies the requirements for the bench test (hereinafter referred to as the ball drop test) using the lifting-type cyclic impact method to determine the fatigue life of cast grinding balls in multiple impact tests, the failure judgment, the test procedure, and the determination of the impact fatigue life (number of cycles) of cast grinding balls. This standard is applicable to the inspection of cast grinding balls used in ball mills in the industrial field (grinding balls used in other mills can be used as reference). This standard serves as one of the test methods for determining the impact fatigue life (number of cycles) of cast grinding balls with a drop height of 3.5m (higher drop heights can be used as reference).
