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.
Laboratory Ball Mill is primarily designed for grinding pigments. The material is ground at a specific speed by using a specific quantity of grinding media (steel balls) for a specific period. The equipment is used for making the ground cement samples in the laboratory. Apart from the cement industry it is also used in the paint plastic
The Basic Static Load Rating is an axially applied static load that causes a permanent deformation on steel balls and screw groove as a sum in the amount of 1/10 000th of the ball diameter. The life of a ball screw can be calculated. Overdesigning the life parameter will result in unnecessarily high costs and excessive size of the mechanism.
