where d 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.

Size reduction from to mm for hardwood specific energy requirement for knife mill is two times lower than for hammer mill, and vice versa for corn stover. It is also worth noting the typical situation where the authors use term "ball mill" for another type of equipment that uses balls as grinding bodies.

An attritor mill, also known as a stirred ball mill, is a type of milling equipment used for grinding and mixing materials. It is commonly used in the production of ceramics, paints, and other materials that require fine grinding. How Does an Attritor Mill Work? Attritor mills work on the principle of agitated grinding.

In attritor mills, milling balls may jam causing an increased resistance to the impeller's rotation. The impeller may, therefore, instantaneously slow down, quickly returning to its preset rotation rate. ...
