Discharge port adjustment


Normal operation, through the hydraulic pump on the spindle cylinder oil or oil, so that the spindle up or down, rolling sand and broken wall between the distance to narrow or increase, adjust the discharge port size.


Over iron and clear cavity


When there are unbreakable foreign bodies through the crushing chamber or for some reason the machine overload, the hydraulic insurance system to achieve insurance, hydraulic oil into the accumulator, the spindle down, the discharge port increases, foreign body from the crushing chamber, the accumulator will oil Pressure back, crusher normal operation. If the foreign body card in the mine mouth, you can use the cavity system, so that further increase the discharge port, so that foreign body discharge crushing chamber. Under the action of the hydraulic system, the discharge port automatically reset, the machine back to normal work.


Single cylinder hydraulic cone


How to maintain the hydraulic system of the cone crusher?


1, to ensure the internal cleaning of the cone crusher, ore processing more dust, so the use of the process to pay attention to the removal of dust, but also to prevent water into the hydraulic oil.


2, to ensure the cleanliness of the hydraulic system, it is recommended to use the same type of hydraulic oil for cleaning, otherwise, may cause damage to the cone crusher.


3, the replacement of hydraulic oil, it is important to note that when adding hydraulic oil must use the filter, but also to ensure that the filter clean. When refueling is appropriate, you need to follow the specified range of oil level.


4, pay attention to the replacement time of hydraulic oil is recommended in the cone crusher just shut down soon, while the hydraulic oil is still hot when the replacement, which is conducive to the oil and sediment precipitation clean, and then injected into the new hydraulic oil.



Multi - cylinder hydraulic cone


From the above maintenance matters, we see that the replacement of hydraulic oil in the cone crusher hydraulic system maintenance plays a very important role. So, how to judge whether the hydraulic oil should be replaced?


Mainly to see "three elements":


1, the degree of oxidation

Usually with the new hydraulic oil color will be relatively shallow, there is no obvious smell, but with the use of time, long-term high temperature oxidation, can deepen the color of hydraulic oil, if found cone crusher hydraulic oil color was dark brown, And accompanied by a smell that oil has been oxidized, need to replace the new oil.


2, water content

Water content. How much of the moisture content of the conical hydraulic oil affects its lubrication performance. When there is a lot of water into the hydraulic oil, because the water is not blending, so when mixing will form a turbid mixture, then we need to replace the hydraulic oil to avoid the impact of conical breaking performance.


3, impurity content

Impurity content. Cone broken in the course of work, due to continuous collision, grinding between the various components, it is easy to produce debris, will inevitably enter the hydraulic oil. If the hydraulic oil contains a lot of impurities, not only will the quality of decline, but also may make the cone broken parts damage. So after the use of hydraulic oil in a period of time, we must pay attention to see the content of impurities in hydraulic oil.


Above is the cone crusher hydraulic system maintenance of small knowledge, in the process of using the cone or to pay attention to the maintenance of equipment to ensure the normal and efficient operation of the equipment.
