Multi-cylinder hydraulic cone crusher

The multi-cylinder cone crusher is a typical crushing device for medium and fine crushed hard materials. When working, the moving cone makes a swinging motion along the inner surface. Close to the fixed cone, the material is crushed by the extrusion and bending of the moving cone. When the moving cone is deflected, the broken material falls from the bottom of the cone due to gravity. The crushing and discharging processes are successively performed sequentially along the inner surface. The lock protection cylinder is composed of a plurality of lock protection cylinders, an over-iron protection accumulator, a buffer accumulator group and a pipeline. The lock protection cylinder mainly functions as iron protection and cleaning the crushing chamber. Each two hydraulic cylinders are equipped with a buffer accumulator. When the normal crushing is used, the adjusting ring jumps due to a few hard materials during the buffering.
