Research kinetic of motion of milling bodies in ball mill

The article considers topical issues of energy saving in cement production with the use of a technological grinding complex which includes a press roller grinder and a ball mill. Rational conditions of grinding are proposed for pre-shredded material through the installation of blade energy exchange devices (BEED) in the mill drum. The loading level in the first chamber varies periodically
