Gold mining ball mills are grinders that are used to reduce the size of ore materials by means of compression and impact. They are cylinder-shaped devices, filled with grinding balls, which rotate on a horizontal axis. As the balls move around the cylinder, they crush and grind the ore materials, resulting in a fine powder. ...
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
