Through the advanced design, the cavity shape of the MRC series multi-cylinder hydraulic rolling bearing cone crusher is optimized, which makes the gradation of the produced stone better and increases the throughput. This series of products is suitable for various fields such as metal and non-metal mines, building materials, and chemical raw materials.

During the operation of the MRC series multi-cylinder hydraulic cone crusher, the moving cone performs a swinging motion along the inner surface. The material close to the fixed cone is crushed by the extrusion and bending of the moving cone; the broken material falls from the bottom of the cone due to gravity at the place away from the moving cone. The whole crushing and unloading process is carried out continuously and sequentially along the inner surface. The locking protection oil cylinder is composed of several locking protection oil cylinders, iron protection accumulators, buffer accumulator groups and pipelines, and mainly plays the role of iron protection and cleaning of the crushing cavity. Every two hydraulic cylinders are equipped with a buffer accumulator, which is used to absorb the jumping impact of the adjustment ring caused by a small number of hard materials during buffering during normal crushing.
