Friction In Cement Mill Grinding Media

Nonmetallic grinding media they have great wear rate generally better than 90 or 995 995 alumina balls have the highest alumina content for a moderate price the 5 impurity is mgo that is added to inhibit grain growth during sintering in the kiln there is less than 01 silica in the media

Method of balls rolling on ball rolling mills is one of the most modern production methods 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 1015 to reduce the consumption of metal
