Rod Mill: The grinding media is grinding cylpebs and grinding rods. 3. Ceramic ball mill: The grinding medium is ceramic balls. According to the length-to-diameter ratio of the drum, the ball mill can be divided into: 1. Ball mill: A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. 2.
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 …
