Tumbler Ball Mills - Powder Metallurgy - Beyond Discovery
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.

Grinding Mill speed is one of the factors affecting the character of the cascading charge. As shown in the illustrations, the lower the percentage of critical speed, the smoother the flow of balls from top of charge to bottom. Higher percentage of critical speed is used for impact grinding of large feed.

With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These actions apply crushing, attrition and abrasion comminu-tion processes to reduce primary-crushed ores down to ball-mill sized feed.
