Principle of Ball Mill : Ball Mill Diagram. • The balls occupy about 30 to 50 percent of the volume of the mill. The diameter of ball used is/lies in between 12 mm and 125 mm. The optimum diameter is approximately proportional to the square root of the size of the feed. The shell is rotated at low speed through a drive gear (60-100 rpm) and ...We have completed a 10.5 x 22 ft ball mill In NC. We only relined the ball mills cylinder/barrel this time around. The reason for that is the end walls last twice as long as the life of one barrel lining. The barrel lining on the ball mills is 2 1/2 inch thick and the end walls are 6 inches. We also have completed a mill of the same size in Texas.

Advantages and features of the ceramic ball mill. The grinding fineness depends on the milling time.
