Oil Resistant Multi Cylinder Hydraulic Cone Crusher Temperature Resistant Portable Cone Crusher

The HP Series represents our company's success in adopting world-class hydraulic cone crusher technology from Europe and the United States, followed by relentless design refinement. We have carefully balanced crushing speed, eccentric throw, stroke length, crushing force, and chamber geometry so that every element works in harmony. The result is a machine that delivers higher output and superior product quality whether you are doing medium, fine, or ultra-fine crushing. This crusher is built to last and perform day after day. It offers high capacity, extensive automation, easy upkeep, outstanding particle shape, and minimal long-term expense for wear components. You will find the HP Series working reliably in sand and gravel operations, mines, metallurgical facilities, building material plants, and anywhere else that requires crushing hard rocks and stones.
The machine's power transmission system is engineered for smoothness and strength. A high-strength one-piece cast frame forms the backbone, while the main shaft comes from high-strength alloy steel produced through precision casting and forging. Inside the drivetrain, high-precision bevel gears keep vibration to a minimum. Flexible supports between the steel structure and the foundation further reduce transmitted vibration, which lowers your foundation construction costs.
When it comes to operating expenses, the HP Series delivers meaningful savings. The crushing chamber follows the inter-particle laminate crushing principle and runs at an optimal speed that maximizes energy utilization. Unlike conventional crushers that rely on single-particle breakage, this machine allows material to fracture not just against the liners but also against other pieces of material. That shift produces more fine material and a higher percentage of cubical particles, while sharply reducing the amount of flat and elongated pieces. The well-designed chamber profile, combined with the protective layer of material that builds up during crushing, keeps wear parts from wearing out quickly. Additionally, both the mantle and the bowl liner are manufactured from high-manganese steel, which extends their working life and significantly lowers costs over many years of operation.
Production efficiency gets a major boost from the intelligent pairing of high swing frequency and generous eccentric stroke. This combination dramatically increases the throughput capacity across the entire HP Series. A hydraulic motor drives the adjustment sleeve — the part that holds the fixed cone liner — allowing operators to set the discharge opening with precision. Once set, the machine maintains a consistent discharge opening during production, avoiding the closed side setting fluctuations that plague single-cylinder crushers where the main shaft moves up and down.
The HP Series also handles heavy loads with confidence. It uses a fixed main shaft arrangement, meaning the eccentric bushing rotates around a stationary shaft. Because the main shaft does not move while the crusher is running, its full strength is preserved, stress distributes more evenly, the moving cone stays stable, and component life is extended. This design achieves higher installed power in a more compact package while weighing significantly less than traditional cone crushers. The reinforced frame, the cantilevered high-strength fixed shaft, and the hydrodynamic lubrication system with bronze bushings all contribute to exceptional load capacity — even in harsh crushing environments filled with vibration and dust.
The sealing system is both reliable and effective at minimizing downtime. If tramp iron passes through the chamber or the machine stalls momentarily, the bidirectional tramp iron release hydraulic cylinder automatically ejects the material, letting the metal piece exit without human intervention. A large hydraulic cavity clearing stroke, which works independently of liner wear, greatly reduces the manual effort needed to clear blockages. The XHP model adds a spherical floating seal to the existing T-U type seal. This, combined with a unique thin oil lubrication system and positive pressure dust seal, provides much more dependable sealing. It eliminates common failures like oil-water mixing — a frequent problem with spring cone crushers — and keeps dust out of the lubricating oil, extending both lubricant life and component life.
Flexibility comes standard. Each HP model supports multiple chamber types — Fine, Medium, Coarse, and Extra Coarse. Switching between them requires only a few parts: the corresponding liners, the belt pulley, and the auxiliary ring. You can even convert a standard coarse cavity into a short-head extra-fine cavity. Product gradation can be adjusted by changing the drive shaft speed, maximizing the value you get from the equipment and giving it remarkably wide adaptability.

Q: How often should the lubricating oil be changed?
A: Oil change intervals depend on operating conditions and oil quality monitoring results. The real-time monitoring system tracks oil temperature, pressure, and flow to help determine replacement timing.
Q: How long does liner replacement take?
A: Thanks to the self-locking design (wedge plate for concave, self-locking bolt for mantle) and no-filler installation, replacement is significantly faster than traditional crushers. The adjustment sleeve can be rotated out for easy access.
Q: Are spare parts readily available?
A: Yes. Sichuan Xinyida Machinery Co., Ltd. maintains an inventory of commonly worn parts, including mantles, bowl liners, and main shaft components.
