This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.
where d b.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.

The quality of every product or material analysis depends on the quality of the sample preparation. It is therefore extremely important to consider all the individual milling parameters in order to make an informed choice: material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts – all these …
Ball Mill Refining & Liquid Conching. Chocolate and compound coatings can be produced using distinctly different methods and equipment. In addition to conventional roll refining systems (with 'dry' conches) Kocotek also specializes in modern ball mill based systems (with 'wet' conches). We are also uniquely specialized in 'hybrid ...
· A ball mill also known as pebble mill or tumbling mill 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 mill volume and its size depends on the feed and mill size.
· Both solid shear (e.g. bead mill) and liquid shear (e.g. high- pressure homogenizer) based methods of cell disruption have proven successful on a large scale. The solid shear methods may involve either a grinding action as in a ball mill or may involve extrusion of frozen cells, either alone
