Advanced design of moveble cone armor in cone crusher for mining industry

This article describes a schematic diagram of a secondary cone crusher that is used in mining enterprises and ways to increase the efficiency of the grinding process by modernizing the armor of the crushing cone. The basis for the development of a mathematical model was the digital twin of a medium crushing cone crusher with an upgradeable crushing cone armor design, developed in the NX CAD/CAM/CAE system. This modernization of the design of the armor of the crushing cone is aimed at increasing the angle of capture of the machine and increasing productivity by reducing the amount of premature loss of large pieces from the working chamber of the crusher. When material enters the working area of the crusher, most often the flaky-shaped material falls into the discharge opening. Modernization of the armor of the crushing cone makes it possible to contain it due to a heel-shaped protrusion at the base of the cone, and an increase in the grip angle allows increasing the volume of the working chamber of the cone crusher. Basic mathematical calculations of the gripping angle made it possible to design a digital twin of the crusher, which was later used to carry out strength calculations using the finite element method in the CAD / CAM / CAE-system NX of the crushing cone assembly, which made it possible to select rational modes of operation of the cone crusher for crushing of rocks and minerals. Based on all calculations, a parameterized cone armor model was created, the parameters of which vary depending on the value of the specified capture angle.
