How do lubrication cone crusher?

Cone crusher lubrication of a direct impact on the health of the machine parts and the length of life, it can reduce friction and wear, but also can play a cooling, to prevent corrosion and flushing action. Therefore we need to do lubrication crusher.

Cone crusher can be used for centralized lubrication cycle, reasonable lubrication technology directly affect economic performance cone crusher. Lubricating oil lubrication oil station of two routes into the crusher, all the way through the frame bottom bracket cover into the hole into the lower body lubricated disc, bushings, thrust bearing bushing, and by the middle of the spindle bearing bore to bowl and bevel gear, bevel small gear lower part of the body bore back into the tank, the other way into the pipe rack shaft, drive shaft bearing lubrication at both ends, respectively, back into the tank from the creel dust cover and the lower part of the small bevel gear. In order to ensure good lubrication, can strengthen the main
lubrication management from the following aspects:
 1) Depending on the season climate, choose a different lubricants.

2) oil pressure is generally controlled at 0.08 ~ 0.2MPa, too large or too small will affect lubrication.

3) In order to ensure the crusher during operation get adequate lubrication, lubrication system and crusher electric chain, oil pump must be open before starting the machine, otherwise it will not start the motor when the hydraulic pump is stopped or reduced to 0.05MPa, are send a signal to stop the motor running to ensure that the parts are not damaged.

4) Due to mechanical wear and tear during operation generates a small amount of residue and dust from entering, so that the lubricating oil slowly dirty, oil qualitative change bad. To this end, the timing of the lubrication oil station cleaning, oil change 3 to 4 months time.

5) timely start cooling means. Cooling device can be used at any time when necessary to start to control the oil temperature is below 50 ℃.

6) water to eliminate dust and dirt from entering lubricants. If lubricating oil containing excessive ash and moisture, it will greatly reduce the lubricating effect, affect the performance of parts of life and machines. To prevent dust from entering, crusher dust seal means provided by the free end of the dust-bowl-shaped ring is inserted in the annular ditch, and use it to block the dust into the water and with the water discharge, also installed on the outside of the gutter rubber band with a layer of dust, dust it with a bowl-shaped stopper ring dust exposure play a role in isolation. In order to prevent dust and water along the periphery of the bowl-shaped bearing seat inflow lubrication system, in addition to strictly control the amount of water to the outside, but also in the periphery of the bearing seat plus welding circle downward sloping impermeable plate, so the overflow from the ring ditch impermeable to water was blocked plate to the outside of the body, with the ore discharge.
