With an ever growing scope of coal sizing and crushing in coal preparation the reduction of energy and metal consumption, as well as the enhancement of the equipment operation reliability and efficiency acquire greater importance. Over recent 20–25 years some important results have been achieved in Russia in the development of efficient crushing and grinding equipment, autogenous grinding mills in particular. This type of grinding equipment has significant advantages as compared with other crushing and grinding equipment.
