HP Cone Crusher Lamination Crushing Fixed Shaft PLC Control Cone Crusher

The HP Multi-cylinder Hydraulic Cone Crusher is a new-generation crushing machine developed by Sichuan Xinyida Machinery Co., Ltd. by introducing and absorbing advanced hydraulic cone crusher technology from Europe and the United States. Through continuous design optimization, it perfectly integrates crushing speed, eccentricity, stroke length, crushing force, and crushing chamber profile, delivering higher productivity and superior product quality in medium, fine, and ultra-fine crushing applications.

This crusher is built with a high-strength integrally cast frame, a fixed main shaft made of precision-forged alloy steel, and high-precision bevel gears, ensuring low vibration, smooth operation, and a service life increased by more than 30%. Its laminate crushing principle produces excellent cubical particle shape, increases fine product proportion, and reduces flaky and elongated material, while high-manganese mantles and bowl liners lower long-term wear costs.

The combination of high swing frequency and long eccentric stroke greatly enhances throughput capacity. The hydraulic motor enables precise discharge opening adjustment at a constant CSS, avoiding variations common in single-cylinder crushers. The fixed main shaft design improves stress distribution, stability, and load capacity, while the compact structure supports higher installed power with reduced weight.

Reliable sealing is achieved through thin oil lubrication, a positive pressure dust seal, and a spherical floating seal, preventing oil-water mixing and dust contamination. The bidirectional tramp iron release cylinder and large hydraulic clearing stroke reduce downtime and manual workload. PLC automatic control provides real-time monitoring of oil temperature, pressure, flow, load, and discharge opening, making operation safer and maintenance simpler. With multiple convertible cavity types and filler-free liner installation, the HP series offers flexible, cost-effective crushing for sand and gravel, mining, metallurgy, and building materials industries.
