Enhancement of operating efficiency of grinding equipment

Abstract

The results of the experimental studies on the process of clinker grinding pre-crushed in a press roller mill and in a ball mill equipped with the energy exchangers are described in the article. The effect of clinker grinding pressure on the amount of deagglomeration forces of its compacted plates is determined depending on the direction of force exertion. The designs of energy-exchange devices are proposed, which make it possible to create an effective power action of grinding bodies on the grinding material. The effect of load factors of the grinding bodies of the first and second ball mill chambers, their lengths, inclination angles and mutual arrangement of energy exchange devices on the output parameters of the grinding process was studied and their rational values were obtained. Comparative tests of cement samples obtained in the energy-saving machines have made it possible to state that their beam strength for the compression and bending is 15-20% higher compared to the traditional way of grinding.
