Investigations were carried out in a laboratory having the of DxL = 160x200 mm with a ribbed inside surface of the drum. The loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.
A , a type of grinder, is a cylindrical device in grinding or mixing materials like ores, chemicals, ceramic raw materials and paints. More information →

A also known as pebble or tumbling is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the volume and its depends on the feed and .
is the key equipment for re-crushing the materials after they are primarily crushed. is widely for the dry type or wet type grinding of all kinds of ores and other grindable materials in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals, and glass ceramic industry.
· a feed of about 15 mm ½ in. or finer and product is very fine with no actual grind limit indicated. Examples include in mineral dressing processes, paints, pyrotechnics ...
are generally to grind material 1/4 inch and finer, down to the particle of 20 to 75 microns. To achieve a reasonable efficiency with , they must be operated in a closed system, with oversize material continuously being recirculated back into the to be reduced.
Ball Mills. The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds.
are a fundamental part of the manufacturing industry in the USA as well as around the world. crush material into various sizes and extract resources from mined materials. Pebble are a type and are also to reduce the of hard materials, down to 1 micron or less.

The rods grind the ore by tumbling within the the , similar to the grinding balls in a . To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod accept feed up to about 50 mm 2 in. and produce a product in the range of 3000 to 270 mm –4 to –35 mesh.
F 80 is the circuit feed in micrometers. Rod . A rotating drum causes friction and attrition between steel rods and ore particles.  But note that the term rod is also as a synonym for a slitting , which makes rods of iron or other metal. Rod are less common than for grinding ...
