The article deals with the production of construction materials and products based on them, the main ones of which are cement, concrete, brick, stone, lime. The source for obtaining construction materials is natural resources that are subjected to various technological processes: grinding, classification, dosing, mixing, molding, heat treatment. The most energy-intensive process is grinding. The main equipment for grinding construction materials are ball-tube mills, which are actively used in industry and are constantly being improved. The main issue of improvement is to reduce the power consumption of a ball-tube mill with cross-longitudinal movement of the load. A comparative analysis and the possibility of using the known methods for calculating the power consumption of the drive of a ball-tube mill with cross-longitudinal movement of grinding bodies is given. The calculation scheme of the ball-tube mill, equipped with an inclined partition, is considered, and a detailed analysis of the mode of motion of the grinding bodies is described and given. Conclusions were obtained about the change in the value of power consumption of the ball-tube mill drive from minimum to maximum, due to the change in the level of the grinding bodies in both chambers of the mill during the cycle from maximum to minimum. Generalizing conclusions were made and it was proposed to reduce the mass of grinding bodies in proportion to the value of additional power consumption, in order to reduce the amplitude of the torque fluctuation on the shaft of the crushing cylinder.
