Notes of Cone Crusher Lubrication System

(1) The lubricating oil goes into the cone crusher by two paths. One goes in from the bottom oil hole of cone crusher, and then divides into three directions to the inside and outside of the hollow eccentric shaft, the middle oil hole of the main bearing and the bowl type bearing, going through the hole lubricating big and small gear, and then the oil will return from the bottom oil returning hole of the small bevel gear. The other oil path is from the hole of the driving bearing shelf, lubricating the driving bearing, and its oil returning is also from the oil returning hole of the small bevel gear and the shield. The oil returning goes back to the oil box from the single oil pipe.

(2) In order for the normal work of cone crusher, when there is no heating equipment inside the plant in winter, an electric resistance heater is installed in the oil box in order to improve the temperature of the oil; in summer, when the temperature of the oil increases, the customer can lubricate the machine making the oil go through the hear exchanger.

(3) Because of long time of working, the temperature of the lubricating oil will increase, but it can never be higher than 60℃, otherwise, the worker should rapidly stop the cone crusher and examine the reasons and eliminate the fault.

(4) The oil pressure must reach 0.8-1.5kgf/cm2. Only when the lubricating oil reaches its lubricating point, can the main motor be started. If the oil pressure is below 0.8kgf/cm2, the control system of the machine will send a signal and immediately stop feeding materials, at this time, the workers will have to find out the reason and resolve the problem.

(5) The pressure of the water going to the heat exchanger is generally 2-3kgf/cm2, and the temperature going into the commutator must be below 28° and the water must be clean.

(6) In winter, if the cone crusher is not working for several hours, the worker must take proper measures to prevent the oil box and the oil in the oil pipe from freezing. The best way is to run without materials in it. When necessary, the resistive heater inside the oil box can be used.

(7) The filter should be always kept clean. If the amount of the oil decreases, which may be caused by oil net blockage, at this time, the machine must be stopped and repaired. When cleansing the pipe of the lubricating system, the place there is likely sediment and smug should examined, such as the knee of the pipe, and make sure cleansing the whole oil pipe or part of the pipe according to the examining result.

(8) When the lubricating system is not working, the oil level in the oil container should reach above the upper limit; when the lubricating system is working, the oil level in the oil container should not be lower than the lower limit. The examination, cleansing and repair of the oil box should not less than once ever year.
