HPC series cone crusher with high-efficiency and hydraulic pressure was widely used in mining, concrete factory, sandstone making, etc. Thepressure resistance strength of the machine is under 350Mpa. Andit is suitable for primary crushing of many kinds of mining and rock such as ores, concrete, fireproof material, bauxite, quartzite, corundum, perlite, ironstone, basalt, etc. Operating principles of Cone Crusher: Cone crusher consists 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, crooked and crushed.
