Abstract
Pipe ball mills are widely used for coarse and fine crushing in producing construction materials. It is a priority to decrease their energy consumption. A mill with dimensions D × L = 3 × 8 m may be used for preliminary crushing in a cylindrical internal classification system, so as to ensure effective coarse milling. The goal is to determine the state of such a device prior to maintenance, after abrasive wear of its components. The magnitude and direction of the forces on the device from the balls and the material being crushed are determined. The most loaded elements are identified: reinforcing lining plates of thickness 0.04 mm. Their stress state is studied with decrease in thickness on account of abrasive wear. The possibility of operating the device to 40% wear of its lining plates is established. Thereafter, repairs are necessary.
