The hydraulic system plays a vital role in the cone crusher, mainly including the following aspects:
1. Adjust the discharge port: The hydraulic system controls relevant hydraulic components, such as hydraulic oil pumps, to inject or drain oil into the spindle cylinder, thereby adjusting the up and down position of the spindle, changing the distance between the moving cone and the outer cone liner, and realizing discharge. Mouth size adjustment.
2. locking function: During the working process of the cone crusher, the hydraulic system can lock the fixed cone or main shaft to prevent the moving cone or main shaft from rotating or falling during ore crushing, ensuring the stability and safety of the crushing process.
3. Cleaning cavity: When the cone crusher stops under load, the hydraulic cavity cleaning system can quickly clean the crushing cavity, reducing equipment downtime and improving production efficiency.
4. Overload protection: When the cone crusher is performing crushing operations, if non-crushed materials enter the gravel cavity, the crusher will increase the crushing force. At this time, the thrust provided by the hydraulic cylinder is lower than the pressure exerted by the thrust plate on the working cylinder. The oil pressure in the high-pressure oil chamber of the working cylinder rises instantly. The throttle valve causes the action valve to work and limits the thrust plate to protect the machine from damage.
5. Automatic discharge of broken materials: When the gravel cavity is filled with gravel, due to the limitation of the large thrust provided by the working cylinder, the piston moves to the right and retracts, and the discharge port of the cone crusher will increase accordingly. When there is foreign matter in the crushing cavity, the hydraulic system can make the moving cone automatically retreat and automatically discharge the foreign matter from the discharge port.
6. Automatic recovery: When the piston of the cone crusher hydraulic system is in the retracted position, the action valve returns the valve core to the upper limit position under the instantaneous high pressure in the upper chamber, stops draining oil into the system, and realizes automatic recovery of the system.
The hydraulic system plays various roles in the cone crusher such as adjustment, locking, cavity cleaning, overload protection, automatic discharge of broken materials, and automatic recovery, ensuring the efficient and stable operation of the cone crusher.
