Summary: Common problems with wear-resistant steel balls during operation include high wear, fragmentation, peeling, out of roundness and eccentric wear, and poor appearance. These issues are mainly caused by the following reasons

Common problems with wear-resistant steel balls during operation include high wear, fragmentation, peeling, out of roundness and eccentric wear, and poor appearance. These issues are mainly caused by the following reasons:

High wear: Mainly due to some manufacturers not having quenching equipment, the wear resistance of untempered steel balls is low, resulting in low product hardness and high wear

Cracking: The main reason is that the composition of the steel ball does not meet the standard, the heat treatment method is incorrect, the appearance is poor, or inferior raw materials are used, resulting in excessive inclusions in the steel ball, which leads to cracking

Peeling: The reason is similar to cracking, mainly because the composition of the steel ball does not meet the standard, the appearance is not good, or the use of inferior raw materials leads to excessive inclusions in the steel ball, resulting in peeling

Out of roundness and uneven wear: Uneven hardness of steel balls is one of the main reasons, and uneven heat treatment can lead to uneven distribution of hardness, resulting in out of roundness phenomenon. In addition, surface quality defects of steel balls such as deep grooves and long handles can also lead to roundness and uneven wear

Poor appearance: The appearance of steel balls has serious appearance defects, such as slag inclusion, sand inclusion, high fuzz, wrinkled skin, etc. These defects are the stress concentration points of steel balls, which can cause them to break or peel off due to stress changes when using the ball mill
