The charge volume of a ball or rod mill is expressed as the percentage of the volume within the liners filled with balls or rods. When the mill is stationary, the charge volume can be quickly obtained by measuring the diameter inside the liners and the distance from the top of the mill inside the liners to the top of the charge. The percentage loading or change volume can then be read off the ...

STEEL BALL MILLS - Genemco

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. If the peripheral speed of the mill is too great, it begins to act like a ...
