# Calculation For Ratating Ball Mill

8.3.2.2 ball mills. the ball mill is a tumbling mill that uses steel balls as the grinding media. the length of the cylindrical shell is usually 1–1.5 times the shell diameter ( figure 8.11). the feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

• Ball Mills - Mine Engineer.Com 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.
