Rod mills, how they function Mine Engineer.Com

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

feed size) and because this is a "single-stage ball mill" calculation, the F80 is actually Size reduction and homogenization with ball mills achieve a very high final fineness down to the submicron range.

Feed Size VS Ball Size Grinding & Classification

Feed Size VS Ball Size (7 replies) One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 = 6 mm would need a ball size of 75 mm.

How Can I calculate new ball size and weight desing for

Mar 10, 2011· Re: How Can I calculate new ball size and weight desing for ball mill. Hi, We have a similar mill. Pregrinding with hammer crusher and mono-chamber mill. Thisis what a proposed based on literture review i did and others agree its more and less correct. But remember it all depends on your mill feed size after pregrinding.
