Abstract
The analysis of the state and direction of development of equipment and technology for grinding materials in the Russian and foreign cement industry is carried out. The equipment used for grinding with ball mills, vertical mills and press-roll grinders is considered. The effectiveness of the use of ball mills and their advantage over other grinding units used in large-capacity production is shown. One of the main directions for the development of the efficiency of the grinding process in ball drum mills has been determined. It consists in the development of intra-mill devices that are aimed at destroying stagnant zones in the feed, intensifying the work of grinding bodies and creating conditions within the mill classification of the crushed material. The design and principle of operation of a ball drum mill equipped with an inclined inter-chamber partition is described. It ensures the transverse-longitudinal movement of grinding bodies in the mill body. The advantages of using an inclined inter-chamber partition are given, which include a reduction in the weight of the mill load and the hydraulic resistance of partition, improved aspiration, reduced power consumption and provision of transverse-longitudinal movement.
