where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/ = % of critical speed. If 100 mm dia balls are replaced by 50 mm dia balls, and the other conditions are remaining the same,

The ball filling ratio, φGB = grinding ball bulk volume / grinding chamber volume, was set to for the standard case. In one set of experiments the filling ratio was increased up to a value of in order to prove its influence on the ball motion. The varied parameters were studied without mill feed in a first step.

The working principle of the vibratory grinding mill is based on intense motion of the grinding balls, with both inertia and centrifugal forces. The energy produced using the Sweco mill is higher than that produced by the ball mill, making it more effective in reducing the particles size to micron or less.

The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock ...
