When unbreakable foreign objects pass through the crushing cavity or the machine is overloaded for some reason, the hydraulic cylinder insurance system achieves insurance, the ore discharge opening is enlarged, and foreign objects are discharged from the crushing cavity. If foreign objects get stuck in the exhaust ore, a cavity cleaning system can be used to discharge the ore. Continue to increase the size, so that foreign matter can be removed from the crushing cavity. Under the action of the hydraulic cylinder, the ore discharge port is automatically reset and the machine resumes normal work. There are three types of coarse crushing cone crusher, medium crushing cone crusher and fine crushing cone crusher, which can be purchased according to different needs of users.

    1. When the cone crusher works, the rotation of the motor is performed by a pulley or a coupling, the cone crusher drive shaft and the cone crusher under the force of an eccentric sleeve to make a swing motion around a fixed point. Therefore, the crushing wall of the crushing cone is sometimes close to and sometimes away from the surface of the mortar wall fixed on the adjusting sleeve, so that the ore is continuously impacted, crushed and bent in the crushing cavity to achieve the crushing of the ore.

    2. The motor drives the eccentric sleeve to rotate through the bevel gear, so that the crushing cone rotates. The crushing cone is sometimes near and away from the fixed cone to complete the crushing and discharging. The connection between the support sleeve and the frame is compressed by a spring. When the crusher falls into an unbreakable object such as a metal block, the hydraulic cylinder will compress and deform to discharge foreign objects to achieve insurance and prevent machine damage.

    3. When the unbreakable foreign body passes through the crushing cavity or the machine is overloaded for some reason, the conical crusher hydraulic cylinder insurance system realizes the insurance, and the cone crusher discharge opening increases. Foreign matter is discharged from the crushing cavity of the cone crusher. If the foreign matter is stuck in the ore discharge, a cavity cleaning system can be used to continue to increase the ore discharge so that the foreign matter is discharged from the crushing cavity of the cone crusher.

    4. The cone crusher is automatically reset by the hydraulic cylinder, and the cone crusher machine resumes normal work. The surface of the crushing chamber is covered with a wear-resistant high-manganese steel liner. The size of the discharge opening is adjusted by hydraulic pressure or manually.
