Calculate Sag Wet Ball Mill

Rod mills how they function

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 We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media While the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill The % loading or change volume can then be read off the graph below or

SAGMILLING COM Mill Critical Speed Determination

Mill Critical Speed Determination The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface This is the rotational speed where balls will not fall away from the mill's shell Ball Mills commonly use rubber liners while steel liners are mostly used for larger SAG/AG/Ball mills Marty says liners are prone to metal or rubber contamination and should be replaced to ensure
