cone crushers

Hydraulic cone crushers (sales code: HPC) is a world-class small cone rock crushers designed by our company is a new type of cone crusher with international advanced level by absorbing the Germanic technology. The HPC cone crushers not only improve the productivity and crushing efficiency, but also broaden the application area, the hardness of materials range from limestone to basalt. The HPC cone crushers have a one and only crushing performance in the realm of medium-size crushing,fine crushing and super fine crushing. The HPC cone crushers are the improved type of spring cone crushers and can be used to replace ordinary high pressure cone crushers in the line of mining and construction.It is the most ideal crushers equipment for large stone crushing factory and mining industry.

HPC type cone crusher is the best available choice for the aggregate and mining market and features a unique combination of crusher speed, throw and cavity design. HPC series hydraulic cone crusher is a kind of gyratory crusher. It has a great crushing performance in the work of medium-size crushing, fine crushing and super fine crushing.

SBM HPC series hydraulic cone crushers are suitable for primary crushing of many kinds of mining and rock whose compression strength not higher than 360Mpa, such as iron ore, concrete, fireproof material, nonferrous metal ores, basalt, granite, limestone, sandstone, cobble, bauxite, quartzite, corundum, perlite, basalt etc.
HPC series hydraulic cone crushers are widely used in mining and construction, concrete factory, sandstone making industry.

1) High crushing ratio with high efficiency.
HPC cone crushers introduces “eccentric bushing circum fixed shaft” special working principle, and strengthen the main shaft, which is possible to realize crushing with larger power. Crushing cavity of the HPC cone crushers adopts layer pressure theory and the matching speed will sharply increase the crushing ratio, output, so does the cubic product percentage.
2) Double insurance hydraulic governing system
HPC series hydraulic cone crushers equipped with insurance cylinder, lock cylinder, lock oil cylinder. They not only protect the machinery but can deal with troubles without disassembly the machine parts. So the maintenance is easier than spring cone crushers.
3) New gearing adjusting system
HPC series cone crushers adopts newly hydraulic driving system and function of self lock &wide adjustment.
4) Grease seal and effective labyrinth seal
HPC cone crushers are adjusted by hydraulic device and lubricated by the dilute oil, which is helpful to avoid water jam, and radically eliminate the defect of water and oil in the traditional spring cone crusher.
5) Hadfield's manganese steel is used in mantle and bowl.
Owing to the change of the crushing cavity and the protection of the crushed products, the abrasion decreases, and the service time is 30%-80% longer than traditional cone crushers.

HPC cone crushers consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening.

During operation, the motor drives the eccentric shaft shell to turn around through a horizontal axle and a pair of bevel gear. The axle of crushing cone swings with the force of eccentric shaft shell so that the surface of the crushing wall is close to the roll mortar wall from time to time. In this way, the ores and rocks will be pressed and crooked and crushed.
