Ball mill is a cylinder rotating at about 7080 of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills Grinding media consists balls of 34 sizes 60mm30mm in designed proportions with large sizes in feed end and small sizes in discharge end
Grinding mill speed it should be noted is not absolute not a definite rpm but relative to a quantity called critical speed The critical speed of a mill is defined as the lowest rpm necessary to centrifuge an infinitely small particle next to the shell lining within the mill By equation where CSCritical speed in
Aug 30 2019 22 Rotation Speed Calculation of Ball Mill Critical Speed When the ball mill cylinder is rotated there is no relative slip between the grinding medium and the cylinder wall and it just starts to run in a state of rotation with the cylinder of the mill This instantaneous speed of the mill is as follows
