HP Series Hydraulic Crusher 151mm Hydraulic Cavity Standard Head Cone Crusher

The HP Series multi-cylinder hydraulic cone crusher represents our company's continuous design optimization efforts following the introduction and absorption of advanced hydraulic cone crusher technology from Europe and the United States. By perfectly integrating crushing speed, eccentricity, stroke length, crushing force, and crushing chamber profile, this crusher delivers higher productivity and better product quality in medium, fine, and ultra-fine crushing applications.
Built with robust and reliable construction, this cone crusher offers high production capacity, a high degree of automation, simple operation and maintenance, excellent product particle shape, and low long-term cost of wear parts. It is widely used across sand and gravel, mining, metallurgy, building materials, and other industries for crushing various hard stones and rocks.

The high-strength integrally cast frame, combined with high-precision bevel gears in the transmission system, delivers low vibration and smooth operation. The main shaft, manufactured from high-strength alloy steel through precision casting and forging, ensures durability. With flexible supports minimizing vibration transmission to the foundation, foundation costs are reduced. The optimized structure protects the frame and high-speed rotating balance ring from wear, resulting in low noise, higher transmission efficiency, stronger load capacity, and a service life typically increased by more than 30%.

Designed around the inter-particle laminate crushing principle, the special crushing chamber allows material breakage to occur between particles themselves—not just between particles and liners. This replaces traditional single-particle crushing, significantly increasing the proportion of fine products and cubical particles while greatly reducing flaky and elongated material. The optimized chamber profile and material bed protection during laminate crushing keep wear on wear parts relatively low. Combined with high-manganese crushing mantle and bowl liner, long-term operating costs are greatly reduced.

The reasonable combination of high swing frequency and large eccentricity (stroke) greatly enhances throughput capacity. Unlike single-cylinder crushers where the main shaft moves up and down causing CSS variations, the HP Series uses a hydraulic motor to drive the adjustment sleeve for precise discharge opening adjustment, allowing production at a constant discharge opening.

With a fixed main shaft design, the eccentric bushing rotates around a stationary main shaft. This maximizes shaft strength, improves stress distribution, enhances moving cone stability, and extends component life. The reinforced frame, cantilevered high-strength fixed shaft design, and hydrodynamic lubrication with bronze bushings provide greater load capacity even in harsh environments with high vibration and heavy dust.

When tramp iron passes through or instantaneous stalling occurs, the bidirectional tramp iron release hydraulic cylinder automatically discharges the material. The large hydraulic clearing stroke, independent of liner wear, greatly reduces manual workload for removing blocked materials. The XHP cone crusher adds a spherical floating seal based on the T-U type seal, using a unique thin oil lubrication system with positive pressure dust seal. This eliminates oil-water mixing issues common in spring cone crushers, prevents dust from contaminating lubricating oil, and extends lubricant and component service life.

All parts can be disassembled and maintained from the top or side—no need to dismantle the frame or fastening bolts. The concave liner self-locks through cooperation between the wedge plate and helical inclined surface. The mantle liner uses a self-locking fastening bolt. No filler is required for liner installation. The hydraulic motor can rotate the adjustment sleeve and bowl liner completely out of the support sleeve, making liner replacement cost-effective and convenient.

Each HP Series model supports multiple cavity types. Changing the cavity type only requires replacing a few parts—liners, belt pulley, and auxiliary ring. The crushing cavity can be converted from standard coarse type to short-head extra-fine type. Product gradation can also be adjusted by changing the drive shaft speed, maximizing equipment value and delivering extremely wide adaptability.

The control system adopts centralized automatic control via hydraulic, lubrication, and electrical systems. It enables automatic pressure compensation, multi-mode operation, overload protection, tramp iron protection, discharge opening adjustment, and synchronous cavity clearing. Real-time monitoring of oil temperature, oil pressure, flow rate, load, and discharge opening size makes the equipment safer to operate and simpler to maintain.

Q: What should I do if the crusher vibrates excessively?
A: Check for uneven feed distribution, worn liners, loose foundation bolts, or imbalanced eccentric bushing. 
Q: What happens during a power outage while crushing?
A: The tramp iron release system and hydraulic clearing stroke allow safe discharge of material when power is restored. Manual cleaning is minimized.
Q: How often should liners be replaced?
A: Replacement intervals depend on material hardness, feed size, and operating hours. Regular inspection and monitoring of product quality indicate when replacement is needed.
