High Precision Multi Cylinder Hydraulic Cone Crusher Low Vibration OEM Cone Crusher Main Shaft

The HP Series Multi-Cylinder Hydraulic Cone Crusher represents our flagship crushing solution, developed through the introduction and absorption of advanced hydraulic cone crusher technology from Europe and the United States. Through continuous design optimization, this crusher perfectly integrates crushing speed, eccentricity, stroke length, crushing force, and crushing chamber profile to deliver superior performance in medium, fine, and ultra-fine crushing applications.

Built with robust and reliable construction, the HP Series delivers high production capacity, a high degree of automation, simple operation and maintenance, excellent product particle shape, and low long-term wear parts cost. It is widely used in sand and gravel, mining, metallurgy, building materials, and other industries for crushing various hard stones and rocks.

At the heart of the HP Series lies the inter-particle laminate crushing principle. Unlike traditional single-particle crushing, our specially designed crushing chamber allows material breakage to occur not only between particles and liners but also between particles themselves. This significantly increases the proportion of fine products and cubical particles while greatly reducing flaky and elongated material. The result is excellent product shape with higher commercial value.

The HP Series achieves a reasonable combination of high swing frequency and large eccentric stroke, greatly enhancing throughput capacity. The hydraulic motor drives the adjustment sleeve for precise discharge opening adjustment, allowing production to be carried out at a constant discharge setting. This eliminates CSS variations common in single-cylinder crushers where the main shaft moves up and down during operation, ensuring consistent product quality.

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

The transmission system utilizes high-precision bevel gears, resulting in low vibration. The overall steel structure, combined with flexible supports, minimizes vibration transmitted to the foundation, reducing foundation costs. Typically, service life is increased by more than 30% compared to conventional designs.

The HP Series control system adopts centralized automatic control integrating 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.

Our unique thin oil lubrication system combines with positive pressure dust seal and spherical floating seal for more reliable sealing. This eliminates common failures such as oil-water mixing found in spring cone crushers and effectively prevents dust from contaminating the lubricating oil, extending the service life of both lubricant and equipment components.

In the event of tramp iron entering the chamber, the bidirectional hydraulic cylinder automatically releases the material, allowing the iron piece to pass through without manual shutdown. The large hydraulic clearing stroke, independent of liner wear, greatly reduces the manual workload required for clearing blocked materials.

All parts can be disassembled and maintained from the top or side without dismantling the frame or fastening bolts. The concave liner features a self-locking wedge plate, and the mantle liner uses a self-locking bolt—no filler is required for installation. The hydraulic motor can rotate the adjustment sleeve completely out of the support sleeve, greatly simplifying liner replacement.

Each model supports multiple cavity types. Changing the cavity requires only replacing a few parts such as liners, belt pulley, and auxiliary ring. The crushing cavity can be converted from standard coarse 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.
