HP Multi-cylinder Hydraulic Cone Crusher Hard Rock Crushing Sand Making Crusher

The HP Multi-cylinder Hydraulic Cone Crusher is an advanced crushing machine developed by our company through the introduction and absorption of sophisticated hydraulic cone crusher technology from Europe and the United States. Through continuous design optimization, it achieves a perfect integration of crushing speed, eccentricity, stroke length, crushing force, and crushing chamber profile, resulting in higher productivity and superior product quality in medium, fine, and ultra-fine crushing operations. The machine is widely used in sand and gravel, mining, metallurgy, building materials, and other industries for crushing various hard stones and rocks.

The crusher is built on a high-strength integrally cast frame, with a main shaft forged from high-strength alloy steel and a transmission system using high-precision bevel gears. This combination ensures low vibration, high transmission efficiency, and smooth operation, while flexible supports reduce vibration transmitted to the foundation and lower foundation costs. The optimized structure provides greater strength and typically extends service life by more than 30%. Its special crushing chamber, designed on the inter-particle laminate crushing principle and matched with an appropriate rotational speed, replaces traditional single-particle crushing. Material is crushed not only between particles and liners but also between the particles themselves, significantly increasing fine products and cubical particles while reducing flaky and elongated material. High-manganese mantle and bowl liner further reduce wear and lower long-term operating costs.

A reasonable combination of high swing frequency and large eccentricity greatly enhances throughput capacity, and the hydraulic motor drives the adjustment sleeve for precise discharge opening adjustment, enabling production at a constant discharge opening. The fixed main shaft design improves stress distribution, enhances moving-cone stability, and extends component life, while the compact structure achieves higher installed power with significantly reduced weight. The bidirectional tramp iron release hydraulic cylinder automatically discharges tramp material, and the large hydraulic clearing stroke, independent of liner wear, greatly reduces manual chamber cleaning. Thin oil lubrication combined with positive-pressure dust sealing and spherical floating sealing provides reliable protection against oil-water mixing and dust contamination, extending lubricant and component life.

All parts can be disassembled and maintained from the top or side without dismantling the frame, and advanced liner fixing technology enables self-locking installation without filler, greatly simplifying liner replacement. Each model supports multiple cavity types, allowing conversion from standard coarse to short-head extra-fine by changing only a few parts, with product gradation adjustable via drive shaft speed. The PLC automatic control system integrates hydraulic, lubrication, and electrical systems, providing automatic pressure compensation, multi-mode operation, overload protection, tramp iron protection, discharge opening adjustment, synchronous cavity clearing, and real-time monitoring of oil temperature, oil pressure, flow rate, load, and discharge opening size, making the equipment safer to operate and simpler to maintain.
