The gyratory crusher belongs to a kind of cone crusher. It is mainly used for coarse crushing of ore. It squeezes, splits and bends the material through the rotating motion of the crushing cone in the cone cavity inside the shell.

Its upper end is supported in a bushing in the middle of the beam, while the lower end is put into an eccentric hole of the bushing. When the bearing rotates, the crushing cone rotates eccentrically around the mechanical center, making its crushing action uninterrupted, so its working efficiency is higher than that of the jaw crusher.

The gyratory crusher can use two ways to adjust the discharge opening and overload insurance: one is to use a mechanical method, and there is an adjusting nut on the upper end of its main shaft. As long as the adjusting nut is turned, the crushing cone can be lowered or raised. , so that the discharge opening becomes larger or smaller accordingly.

When overloaded, safety is achieved by cutting off the safety pin on the drive pulley; the second type is a hydraulically driven hydraulic rotary crusher, whose main shaft is located on a plunger in the hydraulic cylinder, and can be adjusted by adjusting the plunger down. The amount of oil can make the crushing cone move up and down, and then change the size of the discharge hole. When overloaded, the downward pressure of the main shaft will increase, which will promote the hydraulic oil under the piston to flow into the accumulator in the hydraulic transmission system, so that the crushing cone will also descend accordingly, thereby expanding the discharge port. At the same time, the non-broken objects (ironware, wood blocks, etc.) that will enter the crushing cavity together with the materials will also be discharged, so as to achieve the purpose of insurance.

The rotary crusher is a kind of coarse grinding equipment. Compared with the jaw crusher, its advantage is that its crushing process is along a circular ring-shaped crushing cavity, so it has higher efficiency and lower power consumption. more stable jobs. Suitable for crushing crumb materials. From the particle size distribution curve of the finished product, it can be seen that the particle size of the discharge hole is smaller than that of the jaw crusher, and the particle size is more uniform.

The rotary crusher is suitable for enterprises and coal mining plants with large output.
