Study of process of materials grinding in energy-saving complex

The article presents the results of the analysis of the kinetics of the grinding process in a ball mill. The operating modes of grinding loading at various schemes of energy exchange devices installation, in a drum of a ball mill are defined. It is established that the nature of the dynamic action of grinding media in the mill drum is significantly influenced by the mutual location of the energy exchange devices both in the longitudinal and in the cross section of the mill body. The results of experimental studies on the process of grinding the material in an energy-saving complex include: a press roller grinder and a ball mill equipped with energy exchange devices. The influence of load factors of grinding bodies of the first and second chambers of the ball mill, their lengths, angles of inclination and mutual arrangement of energy exchange devices on the output parameters of the grinding process is studied. Their rational values are obtained.
