Ball mill

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Apr 15, 2021 · How do you calculate ball mill speed? The formula for critical speed is CS = 1/2π √(g/(Rr) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = /√(Rr). Dry mills typically operate in the range of 50%70% of CS and most often between 60%65% of CS.
