Mineral processing is the process of selecting useful minerals in the mineral materials collected according to the differences in physical properties, physical and chemical properties and chemical properties of various minerals. The implementation of this process is called a mineral processing machine. Mineral processing machinery is divided into crushing, grinding, screening, sorting and dewatering machinery according to the mineral processing flow. Crushing machines commonly have jaw crushers, gyratory crushers, cone crushers, roll crushers and impact crushers. The most widely used grinding machines are cylindrical mills, including rod mills, ball mills, gravel mills and ultra-fine laminated self grinding machines. Inertial vibrating screen and resonance screen are commonly used in screening machinery. Hydraulic classifier and mechanical classifier are widely used classification machines in wet classification operation. Separation flotation machinery commonly has full section air lift type micro bubble flotation machine, and the dehydrating machinery is famous for multi frequency dewatering sieve tailings dry drainage system. The most famous crushing and grinding system is the ultra-fine laminated self grinding machine.
