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.

A planetary ball mill is known to install pots on a disk, and the pots and the disk are simultaneously and separately rotated at a high speed. The high speed of rotation of the pot and revolution of the disk make the balls move strongly and violently, leading to fine grinding of a product due to generation of large ball impact energy.

Ball Mills In ceramics, ball mills are used to grind down materials into very fine particles. Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. During milling, the porcelain balls pulverized the materials into an incredibly fine powder.
