234mm Multi Cylinder Hydraulic Cone Crusher Flexible Thin Oil Cone Crusher Machine

Developed through the introduction and absorption of advanced hydraulic cone crusher technology from Europe and the United States, the HP Series represents our company's commitment to continuous design optimization. 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.

The HP Series features robust and reliable construction, 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 in 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, results in low vibration. The main shaft is manufactured from high-strength alloy steel through precision casting and forging. Flexible supports minimize vibration transmitted to the foundation, reducing foundation costs. The optimized structure protects the frame and high-speed rotating balance ring from wear, ensuring low noise, higher transmission efficiency, stronger load capacity, and smoother operation. Service life is typically increased by more than 30%.

The special crushing chamber is based on the inter-particle laminate crushing principle. Material breakage occurs not only between particles and liners but also between particles themselves. 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 keep wear on wear parts relatively low. The crushing mantle and bowl liner are made of high-manganese materials, greatly lowering long-term operating costs.

The reasonable combination of high swing frequency and large eccentricity (stroke) greatly enhances throughput capacity. The hydraulic motor drives the adjustment sleeve for precise discharge opening adjustment, allowing production at a constant discharge opening. This avoids CSS variations commonly seen in single-cylinder crushers where the main shaft moves up and down.

The fixed main shaft design has the eccentric bushing rotating around a stationary main shaft. This maximizes shaft strength, improves stress distribution, enhances moving cone stability, and extends component life. The structure is more compact, achieving higher installed power while significantly reducing weight. The reinforced frame, cantilevered high-strength fixed shaft design, and hydrodynamic lubrication with bronze bushings provide greater load capacity in harsh crushing environments with high vibration and heavy dust.

When tramp iron passes 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 combined with positive pressure dust seal. This eliminates oil-water mixing issues found in spring cone crushers, prevents dust from contaminating lubricating oil, and extends lubricant and equipment component service life.

All parts can be disassembled and maintained from the top or side without dismantling 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 model supports multiple cavity types. Changing 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 drive shaft speed, maximizing equipment value and delivering extremely wide adaptability.

The control system adopts centralized automatic control via hydraulic, lubrication, and electrical systems, enabling automatic pressure compensation, multi-mode operation, overload protection, tramp iron protection, discharge opening adjustment, and synchronous cavity clearing.
