Multi-cylinder hydraulic cone crusher mainly consists of fixed cone, dynamic cone, eccentric bushing, transmission device, rack device, adjusting ring, feed bin, and adjustment device of discharge port, hydraulic station, lubrication station, special tools and other components. It is developed based on the spring cone crusher and its basic structure is similar with spring cone crusher. Multi-cylinder cone crusher is typical crushing equipment for the medium and fine crushing of hard materials. It is widely used in mining, metallurgy, construction, chemical, power, transportation and other industries.
In the process of working, the dynamic cone does swinging movement along the inner surface. In the near place from the dynamic cone, the materials are crushed by the extrusion of dynamic cone, and in the far place from the dynamic cone, the crushed materials fall down from the bottom of the cone due to gravity. The whole process of crushing and unloading is carried out continuously and orderly along the inner surface.
