Cone crusher has a very wide range of applications in mining production due to its high crushing efficiency, low maintenance cost, and high output. From a broad perspective, cone crushers are divided into spring cone crushers and hydraulic cone crushers, both of which can be used for medium and fine crushing of high-hardness materials.

The hydraulic system of the hydraulic cone crusher is very powerful and has the characteristics of small size, light weight, easy installation, fast response speed, and high controllability. Correct maintenance and care are the conditions to ensure the stable and efficient operation of the hydraulic system of the cone crusher. This article shares three functions of the hydraulic system of the hydraulic cone crusher

1. Discharge port adjustment

During normal operation, the main shaft cylinder is filled with oil or drained through the hydraulic oil pump to move the main shaft up or down, reduce or increase the distance between the mortar wall and the crushing wall, and adjust the size of the discharge port.

2. Iron passing and cavity clearing

When unbreakable foreign matter passes through the crushing cavity or the machine is overloaded for some reason, the hydraulic safety system is used to ensure safety, hydraulic oil is injected into the accumulator, the main shaft falls, the discharge port is enlarged, foreign matter is discharged from the crushing cavity, the accumulator presses the oil back, and the crusher operates normally. If foreign matter is stuck in the discharge port, the cavity clearing system can be used to further enlarge the discharge port and discharge foreign matter from the crushing cavity. Under the action of the hydraulic system, the discharge port is automatically reset and the machine resumes normal operation.

3. Locking

Lock the fixed cone on the adjustment ring to prevent the fixed cone from rotating during crushing. Lift the locking ring, and the positioning bolt on the adjustment ring controls the lifting distance.


Ok, above is all about the three functions of the hydraulic system of hydraulic cone crusher. It plays a critical role in discharge port adjustment, iron passing and cavity clearing, and locking. In a word, it is a irreplaceable part for the hydraulic cone crusher!
