A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. T
Early mills were water powered but mills can also be steam or electric powered. A stamping mill may refer to a factory that performs stamping. See also. Ball mill a horizontal cylinder containing metal balls to crush the material; Hammermill a more modern device that also can crush material to fines.
The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing. Industrial ball mills can be as large as 8.5 m in diameter with a 22 MW motor, drawing approximately 0.0011% of the total world39;s power . However, small versions of ball mills can be found in laboratories where they are used for grinding sample ...
The IsaMill is a stirred medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high throughput mills . Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods. A tube mill is a revolving cylinder of up to five diameters in length used for fine pulverization of ore, rock, and other such materials; the material, mixed with water, is fed into the chamber from one end, and passes out the other end as a slurry .
The ball mill is composed of the main part such as a feeding part, a discharging part, a turning part, a transmission part .
