Hydraulic system plays an important role in cone crusher. Through hydraulic regulation, it can realize direct adjustment of discharge port, prevention of iron overloading, clearing cavity, overload protection and other functions. When conveying unbreakable iron or other materials, the hydraulic system will automatically retreat, while the outlet of the crusher will automatically expand to discharge materials and foreign matter. After unloading, the hydraulic system will automatically reset the ore discharge outlet, and the machine will resume normal work. Therefore, the value and importance of hydraulic system is self-evident, and it is very important to maintain the hydraulic system naturally.

Material crushing, an important point is to choose equipment reasonably according to the material, this is because each equipment has its unique advantages, only reasonable use of these advantages, can achieve the maximum efficiency. Cone crusher speed and large Angle is bigger than spiral broken, compared with screw broken slower motion speed and minor stroke, with faster and more big, the effect of cone crusher chamber inner any moment only 5% of the rocks in a broken state, the rest is in a state of decline, so that the crusher capacity is very big, the corresponding output is high, and was broken only 5%, The device consumes less power.

The structure of hydraulic system of cone crusher is similar to that of hydraulic rotary crusher. The spindle of the crusher is supported by pressure oil, so the oil in and out of the oil chamber will make the spindle rise or fall, so as to achieve the purpose of adjusting the size of the discharge port. Small cone crushing machine adopts manual gear pump, and cone crusher adopts electric gear pump to supply oil to the oil chamber. When adjusting the discharge port, only one person can complete it in one minute. The operation is very safe, there is no need to disassemble the equipment, and no auxiliary facilities
