Ball/pebble mills operate either in open or closed circuit. Open circuit operation is best utilized when: Another stage of grinding follows the mill; Reduction ratio is small; Feed material is already fine and one pass through the mill produces the desired result; Product size control is not critical and oversize material can be tolerated in ...

Wet Ball Mills are Ball Mills that are used widely in the ore beneficiation industry,as well as the building material industry such as glass.. During the producing phase, the material and water are mixed together to grind in the ball mill. Under the effect of the flowing water,the material will get a better flow ability so the processing capacity will be higher.

The unique grinding action of the mill rapidly reduces troublesome 0.5mm particles to submicrometer sizes required for quantitative and qualitative analytical methods. Forty-eight cylindrical grinding elements produce both line contact blows and planar shearing, in contrast to the random contact blows of a conventional ball mill.

Pebble Mills are similar with the Ball Mills. Pebble Mills are the most popular mill designs - furnished with either of three types of linings or extra heavy chrome manganese steel shell. Lined mills are charged with Flint Pebbles, Porox Balls (Silica based), or Arlcite Balls (Alumina based) and unlined mills use Chrome-Molloy Steel Balls.

A Mill is a unit operation designed to break a solid material into smaller pieces. There are many different types of grinding mills and many types of materials processed in them. Historically mills were powered by hand (mortar and pestle), working animal (horse mill), wind (windmill) or water (watermill).

Rod Mills are similar with the Ball Mills xcept they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

Agitated Ball Mills are a variation of regular Ball Mills and are often used for the grinding of wet media. Most of the agitated media mills are used for slurries, only a minority is in industrial use for the fine grinding of dry powders. The grinding energy is transferred into the media by agitation with a rotating stirrer.
