Popis:	In many industries millions of tons of various materials are subjected to fine grinding. It is relevant to improve the quality of final products at minimum power consumption. Vibration mills are widely used to obtain powders with the particle size of the final product of less than 10 microns. Depending on the design of a drive from and the nature of vibrations of a grinding chamber they are divided into mills with harmonic, biharmonic and polyharmonic vibrations. The general disadvantage of such mills is stagnant zones in loading reaching 30% of the grinding body weight. Thus, the efficiency of grinding is reduced. The paper considers a new design of a rotary vibration mill without stagnant zones, which significantly increases productivity and grinding fineness of the final product. It describes the equations that were obtained to calculate the power consumption of a drive and the kinetics of grinding.
