Hydraulic Cone Crusher PSGB-1321 Granite Machine for Hard Rock Secondary Crushing

The Hydraulic Cone Crusher PSGB-1321 brings full hydraulic control to secondary and tertiary crushing of hard, abrasive rock such as granite, basalt and river gravel. Hydraulic cylinders set the discharge opening precisely, provide automatic overload release when tramp material enters the chamber, and allow the chamber to be cleared quickly without manual labor. Combined with a deep crushing cavity and high eccentric speed, the machine achieves a high reduction ratio and an excellent cubical product. The result is higher throughput, better shape and lower wear cost, making it a leading choice for modern, high-capacity aggregate and mining plants.

• Full Hydraulic Adjustment: Discharge opening and crushing cavity are set hydraulically, making changes fast, precise and repeatable for consistent product size.
• Automatic Overload Protection: Hydraulic cylinders release and automatically reset when uncrushable material enters, protecting the machine from damage.
• High Reduction Ratio: A deep chamber and optimized eccentric throw deliver a high reduction ratio and a well-graded, cubical product.
• Laminated Crushing Action: Inter-particle crushing reduces flakiness and stress, producing stronger, better-shaped aggregate for concrete and asphalt.
• Durable Manganese Liners: Bowl and mantle liners made from premium manganese can be rotated to extend life and lower cost per ton.
• Stable High-Speed Drive: Precision gearing and heavy bearings transmit power smoothly, enabling high cavity throughput with low vibration.

Hydraulic cone crushers are used for secondary and tertiary crushing in hard-rock quarries, metal mines and construction aggregate plants. They handle granite, basalt, diabase, iron ore, copper ore and river gravel, and are commonly installed in high-capacity lines feeding screening and sand-making stages.

The crusher is shipped with the hydraulic unit, eccentric assembly and liners protected and the controls crated. A spare liner set and hydraulic filters are available. Units are assembled and test-run before delivery. We provide a twelve-month warranty plus responsive service for hydraulic components and wear liners to keep your plant at high availability.
