Multi-cylinder Hydraulic Cone Crusher Based on some design principles of traditional multi-cylinder hydraulic cone crushers like fixed main shaft, eccentric sleeve rotating around main shaft and lamination crushing, Multi-cylinder Hydraulic Cone Crusher makes a breakthrough on its structure. After optimization, the structure improves the performance and crushing capability a lot. Meanwhile, the hydraulic lubrication system of HPC Cone Crusher not only ensures the stable operation but also makes the system control more intelligent.

The raw material is high strength cast iron, with good mechanical property, as well as good ability of absorbing the energy of crusher's vibration. It's a great help to make the rotation of main shaft running steady, which can continuously stable the output of your crusher. The heat treatment of tempering is applied to release the internal stress. It's a great help to prevent the part's dimension change in the daily operation of your crusher. It obviously can prolong the life of your crusher. The final machining is carried by CNC machine to ensure each dimension tolerance, which helps to make your assembly easy and fast, to improve the efficiency of your production and maintenance.

Cone crusher consist of frame, transmission device( countershaft, countershaft bushing, gear and pinion), main shaft, eccentric shaft, cone,mantle, bowl-shaped bearing, springs and hydraulic pressure station for adjusting discharge opening.

(1) Transmission device: Countershaft assembly is supported by the bronze countershatf bushings, can be dismounted for convenience of maintence. And the gear and pinipn with high strengh and high precision are adopted to ensure the reliable operation of equipment.
(2) Main shaft: Forged form hardened and tempered chrome molybdenum steel particularly large diameter to suit wear-resisting application. High quality copper socket liner can bear high crushing load, and allows the machine working under rigorous condition.
(3) Cone and mantle plate, high manganese steel casting, hydraulic lock device is convenient and reliable.
(4) Spring and hydraulic device: Convenient for adjusting the discharge size, can remove the foreign materials if non-crushable objects came into the crushing chamber.

Reserving unique structures like the fixed axis and the characteristic that eccentric sleeve rotates around the axis, HPT Hydraulic Cone Crusher further optimizes the transmission parts and lubrication and sealing structures. So, this crusher boasts strong holding capacity, bigger installed power, higher efficiency yet lower noises.
