279mm Multi Cylinder Hydraulic Cone Crusher 500KW 44.9t Hydrocone Crusher

HP Multi cylinder Hydraulic Cone Crusher material bed protects liners during work

Our HP Series came from studying the best hydraulic cone crusher technology that Europe and America had to offer, then putting our own continuous improvements into the design. We got the crushing speed, the eccentricity, the stroke length, the crushing force, and the chamber shape all working together as one system. The payoff shows up in two places: you get more production, and the material you produce looks better when you are doing medium, fine, or ultra-fine crushing. This crusher is built tough and works without fail. It gives you high output, runs with little hands-on help, stays easy to service, turns out nice cubical particles, and keeps your wear part costs low over many years. Sand and gravel operations, mines, metallurgy plants, and building material factories all use this machine to crush hard stones and rocks every single day.

The power transmission side of this machine runs strong and smooth. We built it with a high-strength one-piece cast frame. The main shaft comes from high-strength alloy steel that we cast and forge with precision. High-precision bevel gears inside the transmission keep vibration low. Flexible supports between the steel structure and the ground cut down even more on vibration reaching your foundation, which lowers your construction costs. Because we optimized everything, the frame and the fast-spinning balance ring do not suffer much wear during operation. The machine runs quiet, transfers power efficiently, handles heavy loads well, and operates very smoothly. Most of the time, you will see the service life go up by more than thirty percent.

Operating costs come down significantly because of laminate crushing. We designed a special crushing chamber based on the inter-particle laminate crushing principle, and we matched it with a rotational speed that puts out more energy. Here is what makes the difference: instead of just crushing material against the liners the old way, this machine also lets material crush against other material. That means more fine product comes out, more cubical particles show up, and flat or elongated pieces drop way down. The chamber shape works so well that the material itself forms a protective bed, so the wear parts do not wear out quickly. We make the mantle and bowl liner from high-manganese material, which adds even more life and drives long-term costs down.

For high production efficiency, we paired a fast swing frequency with a long eccentric stroke. That pairing gives this whole series a big boost in throughput. A hydraulic motor turns the adjustment sleeve that holds the fixed cone liner, so you can set the discharge opening exactly where you want it. Once set, the machine runs with that constant opening. That means no more closed side setting drift — something you cannot avoid with single-cylinder crushers where the main shaft moves up and down. When it comes to load capacity, the HP Series uses a fixed main shaft design. The eccentric bushing spins around the shaft while the shaft stays completely still during operation. That stillness maximizes the shaft's strength, spreads out stress evenly, keeps the moving cone stable, and helps every part last longer. The whole machine packs more installed power into a smaller, lighter package than traditional crushers. The reinforced frame, the cantilevered high-strength fixed shaft, and the bronze bushing lubrication all work together to handle rough, dusty, high-vibration environments.

The sealing system keeps trouble out and keeps the machine running. If tramp iron passes through or the machine stalls for a moment, the bidirectional tramp iron release hydraulic cylinder automatically pushes the material out. A large hydraulic clearing stroke — one that does not depend on liner wear — means you do not spend much time digging out blockages by hand. The XHP model adds a spherical floating seal on top of the T-U seal, using thin oil lubrication and positive pressure dust seal for better sealing. This gets rid of the oil-water mixing problem that spring cone crushers have, stops dust from getting into the oil, and makes both the lubricant and the parts last longer.

Maintenance could not be simpler. Every part comes apart from the top or the side, and you never need to break down the frame or touch the fastening bolts. The concave liner locks itself in using the wedge plate and the helical slope on top. The mantle liner uses a self-locking bolt. No filler material needed when you install liners. The hydraulic motor can also spin the adjustment sleeve and bowl liner completely out of the support sleeve, making liner replacement fast and cheap. Every HP model supports multiple cavity types — Fine, Medium, Coarse, and Extra Coarse.

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: What is the lead time for ordering a new crusher?
A: Lead time depends on model specifications and order quantity. Please contact our sales team for current production schedules and delivery estimates.

Q: Do you provide on-site operator training?
A: Yes. We provide on-site training for your operators and maintenance staff, covering safe operation, daily inspections, liner replacement procedures, and troubleshooting.
