The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time with only minor warming effects. These ball mills are also suitable for mechano chemistry. Mixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. These ball mills are suitable for dry, wet and cryogenic grinding as

Ball Mill an overview ScienceDirect Topics

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. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.

What is a Ball Mill? wiseGEEK

A ball mill is a grinding device that is used to turn material into fine powder. Ball mills are cylindrical in shape, and are often the grinder of choice when it comes to mashing paints, ores, ceramic materials, and certain hard chemicals. By rotating on a horizontal axis, a ball mill can effectively convert a hard material into a loose powder.

BALL & ROM BALL MILLS Astec Mining

Ball mills accept feed that ranges in size from 80% passing 70mm (ROM Ball Mills) through 15 mm (post a tertiary crusher circuit) to fine feeds of less than 1mm in regrind operations. Products may be as coarse as 0.5 mm or as fine as 40 microns and below. In a ball mill the length may be less than, equal to, or greater than its diameter.
