Shanghai Zenith Mineral Co., Ltd.
What ZENITH is doing is customizing economical and suitable production lines for customers and building brand value.
Cone crusher is widely used in mine production due to its high crushing efficiency, low maintenance cost and large output capacity. Cone crushers are divided into spring cone crushers and hydraulic cone crushers, both of which can be used for the production of medium and fine crushing of high-hardness materials.
In the following part, we mainly introduce how to properly maintain the hydraulic system of the hydraulic cone crusher.
Function of the hydraulic system
To understand how to maintain the hydraulic system of the cone crusher, we must first have a clear understanding of the hydraulic system of hydraulic cone crusher. The hydraulic system on the cone crusher is mainly used to ensure the normal operation of the equipment and adjust the size of the discharge opening.
Adjust the discharge opening: During normal operation, the hydraulic oil pump is used to inject or discharge oil into the main shaft cylinder, so that the main shaft moves up or down, the distance between mantle and concave is reduced or increased, and the size of the discharge opening is adjusted.
Iron passing and crushing cavity cleaning: When unbreakable foreign objects pass through the crushing cavity or the machine is overloaded for some reason, the hydraulic system realizes insurance, the hydraulic oil is injected into the accumulator, the main shaft falls, the discharge opening increases, and the foreign objects are discharged from the crushing cavity, the accumulator presses the oil back, and the crusher operates normally. If the foreign object is stuck in the ore discharge opening, the cavity cleaning system can be used to further enlarge the ore discharge opening, so that the foreign matter can be discharged from the crushing cavity. Under the action of the hydraulic system, the discharge opening is automatically reset, and the machine resumes normal work.
