CH Series Cone Crusher

The CH series cone crusher is a high-performance medium-to-fine crushing equipment for hard materials, widely used in mining and aggregate production, with a capacity up to 2000 t/h and product cubicity ≥85%. It operates via lamination crushing, where the motor-driven eccentric shaft sleeve makes the moving cone swing, crushing materials between it and the fixed cone.​ Structurally, it includes a cast steel main frame, a crushing assembly (moving cone with 42CrMo body and Cr20 liner, segmented fixed cone), a transmission system (eccentric shaft sleeve, bevel gears, variable-frequency motor), a hydraulic control system (6–12 cylinders for discharge port adjustment and overload protection), and lubrication/dustproof systems.​ Key components undergo precision manufacturing: frames and eccentric sleeves via casting (ZG270-500/ZG35CrMo) with heat treatment; moving cone via forging (42CrMo) and machining. Quality control involves material testing, dimensional inspection (CMM, laser scanning), NDT (UT, MPT), and performance tests.​ Installation includes foundation preparation, frame mounting, component assembly, system connection, and commissioning. It delivers reliable performance in large-scale operations
