Dec 10, 2020 Tumbler Ball Mills. In the tumbler mill shown in Fig. 19, the motion of the balls or rods depends on the rotation speed of the chamber walls. Balls may roll, or cascade, down the surface of the charge in a series of parallel layers or they may project, or cataract, into space, falling on the balls and particles at the toe of the charge below.

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.

The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed. Get Price.
