Layered Crushing Hydraulic Cone Crusher Tramp Iron High Production Mobile Cone Crusher

The HP Series Multi-cylinder Hydraulic Cone Crusher is developed by our company based on the introduction and absorption of 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. As a result, it achieves higher productivity and better product quality in medium, fine, and ultra-fine crushing applications.
This cone crusher 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 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.

The multi-cylinder hydraulic cone crusher features a high-strength integrally cast frame. The main shaft is manufactured using high-strength alloy steel through precision casting and forging. The transmission system utilizes high-precision bevel gears, resulting in low vibration. The overall steel structure, combined with flexible supports, further minimizes vibration transmitted to the foundation, thereby reducing foundation costs. The optimized overall structure offers greater strength, effectively protects the frame and the high-speed rotating balance ring from wear during operation, ensures low noise, higher transmission efficiency, stronger load capacity, and smoother operation. Typically, service life is increased by more than 30%.

The crusher employs a special crushing chamber designed based on the inter-particle laminate crushing principle, matched with an appropriate rotational speed to deliver greater energy. It replaces the traditional single-particle crushing principle, allowing material breakage to occur not only between particles and liners but also between particles themselves. This significantly increases the proportion of fine products and the content of cubical particles, while greatly reducing flaky and elongated material. Due to the optimized crushing chamber profile and the protective effect of the material bed during laminate crushing, wear on wear parts is relatively low. The crushing mantle and bowl liner are made of high-manganese materials, further reducing wear and greatly lowering long-term operating costs.

The crusher achieves a reasonable combination of a high swing frequency of the crushing head and large eccentric stroke of the eccentric bushing, greatly enhancing the throughput capacity of this series. The hydraulic motor drives the adjustment sleeve for precise discharge opening adjustment, allowing production to be carried out at a constant closed side setting. This avoids CSS variations caused by the main shaft moving up and down during operation in single-cylinder crushers.

The crusher features a fixed main shaft design, with the eccentric bushing rotating around the main shaft. The main shaft remains stationary during operation, which maximizes its 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 through or instantaneous stalling occurs, the bidirectional tramp iron release hydraulic cylinder automatically discharges the material, allowing the iron piece to pass through the crushing chamber without manual shutdown. The machine features a large hydraulic clearing stroke independent of liner wear, greatly reducing the manual workload for removing blocked materials. A spherical floating seal with thin oil lubrication and positive pressure dust seal eliminates common failures such as oil-water mixing found in spring cone crushers, effectively prevents dust from contaminating the lubricating oil, and extends the service life of the lubricant and equipment components.

All parts of this machine can be disassembled and maintained from the top or side without dismantling the frame or fastening bolts. The concave liner self-locks using a wedge plate and helical surface, while the mantle liner uses a self-locking 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, greatly simplifying liner replacement.
Each model supports multiple cavity types including fine, medium, coarse, and extra coarse. Changing the cavity type only requires 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. Product gradation can also be adjusted by changing the drive shaft speed.

The HP series control system adopts centralized automatic control via hydraulic, lubrication, and electrical systems, enabling functions such as automatic pressure compensation, multi-mode operation, overload protection, tramp iron protection, discharge opening adjustment, and synchronous cavity clearing. It also provides real-time monitoring of oil temperature, oil pressure, flow rate, load, discharge opening size, and other parameters, making the equipment safer to operate and simpler to maintain.
