Safety Insurance of Hydraulic Cone Crushers

Return list

Cone crusher is used for medium crushing and fine crushing. Hydraulic cone crusher has advantages of high production efficiency, low maintenance. Dewo cone crusher machinery  has single cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher. How the hydraulic cone crushers realize the safety when they meet unbreakable materials in operation? The following is he maintenance methods: 

Firstly, let's to know the structure of cone crushers: when the hydraulic cylinder is in normal operation, the main shaft is moved up or down by injecting oil or discharging oil through the hydraulic oil pump, the distance between the mortar wall and the broken wall is reduced or increased, and the size of the discharge port is adjusted.


When there is an unbreakable foreign body through the crushing chamber or for some reason, the hydraulic insurance system realizes the safety. Hydraulic oil is injected into the accumulator, the spindle falls, the discharge port increases, the foreign body is discharged from the crushing chamber, the accumulator presses back the oil, and the crusher operates normally.If the foreign body gets stuck in the discharge port, the cavity cleaning system can be used to further increase the discharge port, so that the foreign body will be discharged out of the broken cavity.Under the action of the hydraulic system, the discharge port is automatically reset and the machine returns to normal operation.
