Ball Mill Introduction . There are three main stages to mineral processing in the mining industry.These are: Comminution (crushing and grinding).; Beneficiation (separation and concentration).; Smelting and refining.; Ball mills are employed in the comminution stage as grinding machines (size reduction).The purpose of grinders in the mining industry is …

1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.
Ball mills are very effective for grinding smooth, aqueous, or oily dispersions by wet grinding since it gives particles of 10 microns or less. Construction of Ball Mill: The basic parts of the ball mill are a shell, balls, and motor Fig.2. A ball mill is also known as a pebble mill or tumbling mill.

Ball mills and grinding tools Cement ball mills are typically two-chamber mills (Figure 2), where the first chamber has larger media with lifting liners installed, providing the coarse grinding stage, whereas, in the second chamber, medium and fine grinding is carried out with smaller media and classifying liners.
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume. Mills are …

synchronous motor driven ball mill. The Benshaw variable frequency drive powers the 4160 volt - 3500HP synchronous ball mill motor during positioning to smoothly rotate the ball mill and bring it to the proper position for maintenance. The customer's previous system utilized multiple DC contactors and a motorized cam switch to position the mill.
Planetary ball mill is a most frequently used system for mechanical alloying since only a very small amount of powder is required. Therefore, the system is particularly suitable for research purpose in the laboratory. The ball mill system consists of one turn disc (turn table) and two or four bowls.

IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).
