Cone crusher hydraulic system maintenance has a coup, the system is safer and the production is more efficient. Due to its high crushing efficiency, low maintenance cost and large output, cone crushing has a very wide application in mine production. From a large perspective, the cone is broken into a spring cone and a hydraulic cone, which can be used for medium and fine crushing of high hardness materials. Today, let's take a look at how to properly maintain the hydraulic system with hydraulic cones.

To understand how the hydraulic system of the cone is broken, we must first have a clear understanding of the hydraulic system with a broken cone. 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.

Discharge port adjustment: In normal operation, the hydraulic oil pump is used to fill or drain the spindle cylinder, so that the main shaft moves up or down, and the distance between the rolling wall and the crushing wall is reduced or increased, and the discharge opening is adjusted.

Over-iron and clear cavity: When there is unbreakable foreign matter passing through the crushing cavity or the machine is overloaded for some reason, the hydraulic safety system realizes insurance, the hydraulic oil is injected into the accumulator, the main shaft falls, the discharge opening increases, and the foreign matter is discharged from the crushing cavity. The accumulator presses the oil back and the crusher operates normally. If the foreign matter is stuck in the discharge port, the clear cavity system can be used to further enlarge the discharge port, so that the foreign matter is discharged out of the crushing cavity. Under the action of the hydraulic system, the discharge port is automatically reset and the machine resumes normal operation.

Maintenance of the hydraulic system of the cone crusher

To ensure the cleanness of the inside of the cone crusher, the ore processing produces more dust, so pay attention to dust removal during use, and also prevent water from entering the hydraulic oil. To ensure the cleanliness of the hydraulic system, it is recommended to use the same type of hydraulic oil for cleaning, otherwise it may cause damage to the cone crusher.

To change the hydraulic oil, it is important to note that the filter must be used when adding the hydraulic oil, and also to ensure that the filter is clean. When refueling, it is necessary to follow the range of the specified oil level.

Pay attention to the replacement time of the hydraulic oil. It is recommended to replace the oil when the hydraulic oil is still hot shortly after the cone crusher is stopped. This will help the oil and the sediment to be discharged, and then inject new hydraulic oil.

From the above maintenance matters, we have seen that the replacement of hydraulic oil plays a very important role in the maintenance of the hydraulic system of the cone crusher. So, how do you know if the hydraulic oil should be replaced? Mainly look at the "three major elements":

The degree of oxidation. Usually the new hydraulic oil will be relatively light in color and there will be no obvious odor, but with the prolonged use time, the long-term high temperature oxidation can deepen the color of the hydraulic oil. If the color of the hydraulic oil of the cone crusher is dark brown, With the smell, the oil has been oxidized and new oil needs to be replaced.

Water content. The water content of the cone-break hydraulic oil affects its lubricating performance. When a large amount of water enters the hydraulic oil, because the water and oil do not blend together, a turbid mixture will form during mixing. At this time, we need to change the hydraulic oil to avoid affecting the performance of the cone breaking.

Impurity content. When the cone is broken during the working process, due to continuous collision and grinding between the parts, it is easy to generate debris, which will inevitably enter the hydraulic oil. If the hydraulic oil contains a large amount of impurities, not only the quality will be degraded, but also the broken parts of the cone may be damaged. Therefore, after using the hydraulic oil for a period of time, be sure to pay attention to the content of impurities in the hydraulic oil.

The above is the small knowledge of the maintenance of the hydraulic system of the cone crusher. In the process of using the cone, it is necessary to pay attention to the maintenance of the equipment to ensure the normal and efficient operation of the equipment.
