Cone Crusher Relief Cylinder

This paper details the safety cylinder (release cylinder) of cone crushers, a core safety component protecting the equipment from overloads by enabling the moving cone to displace via hydraulic oil release and reset. It elaborates on its composition (cylinder body, piston, sealing assembly, etc.) and structure, then outlines the casting process (material selection, mold making, melting, heat treatment, inspection), machining process (rough/finish machining, surface treatment, assembly), and quality control measures (raw material, machining accuracy, hydraulic performance, fatigue life, and factory inspections). The safety cylinder's design, craftsmanship, and quality control are crucial for its reliable operation and the crusher's longevity
