• Ball Mill Maintenance Installation Procedure

    2016-10-19 · While all Ball Mill bushings are scraped in the shop to fit either a jig mandrel or the head proper to which it is to be fitted nevertheless there is a certain amount of seasoning and dimensional change which goes on in the type of metals used. Therefore if high spots are found the mill should be raised the bushings removed and rescraped.
