The falling course of iron balls and ores can produce huge falling impact and autogenous grinding The continuous feeding of ores can create considerable pressure to make ores move from feed opening toward discharge openingThe ball size is one of the critical factors for determining the mill performance of ball mills It is well known that larger balls are needed for the effective breakage of large size particles whereas smaller balls are more effective for the breakage of fine particl Therefore it is a common practice in industry to use a mixture of balls rather than balls of a single size to ensure the
