HP300 High-Performance Multi-Cylinder Hydraulic Cone Crusher for Premium Aggregates

The HP300 offers massive improvements in capacity, product shape, and automation. Its multi-cylinder hydraulic design delivers a higher stroke and rotational speed, which maximizes inter-particle crushing for a more cubical final aggregate. Additionally, it features automatic hydraulic tramp iron clearing and push-button CSS calibration, replacing the labor-intensive spring and manual adjustment layouts.

If an uncrushable object like a steel excavator tooth enters the cavity and stalls the machine, the dual-acting hydraulic cylinders can be actuated to lift the adjustment bowl vertically to its maximum stroke. This opens the crushing pocket completely, allowing the trapped material to drop out safely from the bottom in seconds. The cylinders then return the bowl back to its precise operating setting.

Multi-cylinder hydraulic crushers operate with high energy inputs and tight squeezing pressures. Standard manganese steel can warp or experience rapid surface wear under these conditions. Our Mn18Cr2 alloy (18% Manganese, 2% Chrome) accelerates its surface work-hardening reaction upon rock contact, providing an ultra-hard outer working face while keeping a ductile core to absorb heavy impacts.

Yes! The HP300 is engineered with precision-machined metal-to-metal seating surfaces on the head and bowl. This eliminates the need for pouring traditional epoxy backing material during liner swaps. Maintenance crews can simply drop the new mantle and concave in place and bolt them down, saving hours of maintenance downtime and avoiding hazardous chemicals.

As the manganese liners wear down over weeks of operation, the crushing pocket naturally expands. To compensate, operators use the hydraulic motor system to rotate the threaded upper bowl slightly downward into the frame. This tightens the Closed Side Setting (CSS) back to its target measurement, ensuring your final aggregate output remains perfectly within specification.

The net base machine weight of the HP300 is approximately 15,800 kg. Thanks to its compact vertical profile and lack of bulky external spring arrays, it fits easily into a standard 20-foot GP ocean container, keeping international freight logistics simple and cost-effective.

We support the HP300 Multi-Cylinder Hydraulic Cone Crusher with a comprehensive 12-month structural warranty. This covers the main steel frame casting, eccentric assembly, countershaft, forged main shaft, and drive bevel gears against any manufacturing or material defects. High-wear liners (mantle and concave) are excluded, but replacements are heavily stocked for rapid global delivery.
