A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

Ball Mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. Ball mill is an efficient tool for grinding many materials into fine powder, such as building material, chemical industry etc. There are two ways of grinding the dry process and the wet process.

Ball Mill Application. generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.

The filling rate of the wet type lattice ball mill is generally 40 50%, the filling rate of the overflow type ball mill is generally 35 40%, and the filling rate of the dry type lattice type ball mill is generally 25 35%. The rotation speed of the mill will produce three kinds of steel ball movement modes 1.

Ball Mill Charge volume. The mill power is approximately directly proportional to the charge volume within the normal range. When calculating a mill 40 % charge volume is generally used. In pebble and ball mills quite often charge volumes close to 50 % are used.

A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill. In addition, the agglomerated particles are mixed into the coarse powder in the separator and recirculated through the mill.

Ball Mill Loading Dry Milling. Ball Mill Loading (dry milling) When charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product.

The mill used for this comparison is a 4.4 meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 s.ton per hour. This type two compartment mill is a state of the art shell supported cement finish mill. The torque and time requirements of the mill with the ball

1.The working principle of the ball mill The main working part of the ball mill is a rotary cylinder mounted on two large bearings and placed horizontally. The cylinder is divided into several chambers by the partition plate, and the grinding body of a certain shape and size is installed in each bin.

The Vertimill is always more efficient than a ball mill with energy savings ranging from 30% to greater than 50%. The transition point from the Vertimill to an SMD varies depending on the ore properties but generally is in the range of 20 to 40 microns. A detailed test program can be carried out to determine the optimum energy efficient circuit.

F80 to P80. Therefore, a really energy efficient circuit may mean three stages of grinding instead of only two, and each stage can be slightly smaller and more efficient than one big one, e.g. a SAG mill (or HRC) followed by a ball mill and with a tertiary Vertimill.
