Actual FC Bond Mill Charge Weight versus the FC Bond Weight as prescribed by Fred Bond — Theory Meets Manufacturing Reality 1. Due to the varying tolerance in manufacturing of grinding balls a fraction of an inch in diameter variance on a grinding ball will make a
Bond ball mill test procedure were carried out on crushed 335 mm 6 mesh material at different screen closing sizes 300 m 212 m 150 m 106 m and 75 m The screening process was conducted in four sets of 12inch diameter screens for sufficient amount of time to avoid too much materials fed into the screen at one time ... size the feed to the ...
Even the SAG ball charge needs to be adjusted based on the size and hardness of ore it’s working on. Too many grinding balls can prematurely wear out the grinding balls themselves. Operating a mine mill requires balancing a dynamic set of tradeoffs.
