Forces that are responsible for ball mill

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 0.5 micron or less

    Jun 19, 2015 A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula. The mill speed is typically defined as the percent of the Theoretical

    It is also similar to a ball mill because it uses balls, usually ceramic ones having 5-15 mm in diameter. Because the motion of the balls is independent of gravity, an attritor can handle thixotropic materials and slightly higher viscosity of millbases, but the principle of action and type of forces operating are similar to those of the ball mill
