Cone crusher is widely used in mine production. Its main advantages are high output, low use cost, exquisite structure, simple operation, less maintenance, wide application range and high utilization rate. Among them, the hydraulic cone crusher is improved on the basis of the traditional cone crusher. The crushing capacity is large and the production efficiency is high. The key is the hydraulic system. So what is the role of the hydraulic system of the hydraulic cone crusher?

Hydraulic system cone crusher has three functions:
(1) Adjust the size of the discharge port. The main shaft of the crusher is supported by hydraulic pressure. If the oil volume in the oil pressure chamber increases or decreases, the spindle will rise or fall, so as to adjust the size of the discharge opening.

(2) can discharge the ore in the crushing chamber. When a shutdown accident occurs due to a power outage, etc., the moving cone of the crusher can be lowered by the hydraulic system, and the ore can be discharged from the crushing cavity after the clearance of the discharge opening is increased.

(3) Protect the crusher. For example, when an uncrushed object such as an iron block is mixed into the crushing chamber, the oil pressure in the oil pressure chamber increases to the air pressure of the accumulator, which causes the accumulator to be compressed and the oil from the oil pressure chamber Flow to one side of the accumulator. The crushing cone automatically descends to discharge the unbroken material, and then the crusher automatically returns to the normal working position.
