The General Function of Ball Mills. A ball mill is a grinder used for grinding and blending materials for mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. Appearance. Ball mills have various designs and functions, ranging from laboratory-scale versions to large industrial models.

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 …

3. Analysis of Variant Ball Mill Drive Systems The basic element of a ball mill is the drum, in which the milling process takes place (Figure1). The length of the drum in the analyzed mill (without the lining) is 3.6 m, and the internal diameter is 3.4 m. The mass of the drum without the grinding media is 84 Mg.
Ball mill circuit classification system performance is considered here first because it provides the basis for subsequent characterization of ball mill breakage efficiency. Major design and operating variables in closed circuit ball milling of a specified feed to a desired product size are summarized in Table 1.

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
