Manufacturing process of grinding media balls

Sep 24, 2019 · Transversal rolling of balls from the round billet is economical. It differs from other methods due to the possibility to produce grinding balls on the uninterrupted automated aggregates, which allows 2 to 8 times to increase the output and 10-15% to reduce the consumption of metal. The process involves the following stages:

al, 2009). Analysis of the current production process of grinding balls in Zimbabwe showed that rust, grease and dirt reduce the expected output metal by 24% by weight because they are removed as slag. The heat treatment employed for the grinding balls in Zimbabwean industries is normalizing. The process involves the balls
