Choose Right Speed To Improve Ball Mill Grinding

The theoretical suitable speed of the mill is 76 of the critical speed. The actual mills fluctuated around 76. In the current production when the rotation speed of the ball mill is less than 76 of the critical rotation speed it is called low-speed grinding when the rotation speed is higher than the critical rotation speed of 88 it is called high-speed grinding Speed grinding.

Ball Mills Mine

A Ball Mill grinds material by rotating a cylinder with steel grinding balls causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill. The larger the diameter the slower the rotation.
