Upgrading Revolution Of Hydraulic Gyratory Crusher

Last Update:2020-05-06 11:47:28

Gyratory crusher is a great revolution in crusher industry. From the initial jaw crusher to the present gyratory crusher, such upgrading revolution has brought good experience to the majority of crusher users. The gyratory crusher is a large crushing machine for coarse crushing of various hardness ores or rocks. Its working efficiency is much higher than that of jaw crusher. The current rotary crusher has a capacity of more than 10000 tons per hour and a very large feeding diameter of more than 2000 mm.

There are two ways to realize the adjustment and overload insurance of the discharge port of the rotary crusher: one is to adopt the mechanical way, the upper end of the main shaft is equipped with the adjusting nut, rotate the adjusting nut, the crushing cone can be lowered or raised, so that the discharge port can be enlarged or reduced accordingly, when overloading, the insurance can be realized by cutting off the safety pin on the driving pulley; the second is to adopt the hydraulic way to realize the hydraulic rotary crushing The main shaft of the machine is located on the plunger in the hydraulic cylinder. Changing the volume of hydraulic oil under the plunger can change the upper and lower position of the crushing cone, thus changing the size of the discharge port. In case of overload, the downward pressure of the main shaft increases, forcing the hydraulic oil under the plunger into the accumulator in the hydraulic transmission system, so that the crushing cone will drop to increase the discharge port, and discharge the non crushing materials (iron, wood block, etc.) that enter the crushing cavity with the materials, so as to realize the safety.

Because of the high efficiency of the gyratory crusher, it has been favored by the major ore deposits. The machine has been widely used in the mining industry. Compared with jaw crusher, gyratory crusher has complex manufacturing structure, high price, large size and large floor area, but it has superior performance and large output. These advantages are enough to make up for other deficiencies.
