A collection of 14 cone-breaking problems with high frequency

1、Oil temperature is too high cause: poor oil quality, or insufficient oil; Bearing damage; The ambient temperature is too high, there is no cooling water or cooling water is low; The cooler is blocked. Solution: oil change, or refueling; Replace the bearing; Supply cooling water or increase water pressure; Clean the cooler.

2、Oil temperature and oil pressure rise causes: oil pipe or oil ditch blockage, safety valve failure. Solution: Stop the machine for inspection and repair.

3、 Low oil pressure or indicator no oil flow after the oil pump is started causes: low oil temperature; The tubing is blocked or the oil pump is not working properly. Solution: heating to increase the oil temperature; Repair pipelines or oil pumps.

4、 The oil contains a lot of fine mud and impurities cause: the sealing and dustproof device fails; Water shortage caused by blocked or leaking pipes. Solution: Stop the machine to re-seal or clean and repair, and replace the new oil.

5、 There is water in the oil, and the oil level in the tank rises. The cause is that there is water in the thin oil station. The cooler leaks, and the water pressure is greater than the oil pressure; The water supply is too large or the return pipe is blocked. Solution: Cover the thin oil station, clean the oil tank, replace the oil; Repair the leaking part or replace the cooler, reduce the water pressure, clean the tank, change the oil; Adjust the water supply or clean the return pipe, clean the fuel tank, and replace the new oil.

6、The cause of strong vibration of the crusher: the fixed device of the machine base is loose; The crushing chamber enters the refractory material; Excessive material in the crushing chamber leads to material blocking; Parts are broken or worn; Poor lubrication causes the spindle to be tight with bushing. Solution: fastening bolts, pouring; Control the type of feed, strictly prohibit the entry of non-broken materials; Strictly control the feeding quantity; Stop to check accessories; Replace damaged parts, repair oil pumps and pipelines.

7、 Crusher strong vibration, crushing cone rotation is very high cause: oil shortage between the main shaft and the liner or dust in the oil; The gap of the cone bushing is insufficient; Bowl bearing tile wear or manufacturing reasons, contact surface depth up to the inner circle, conical body sinking. Solution: repair or replace bushing, spindle, etc., and find out the cause of oil shortage, eliminate it; Adjust the bushing gap; Regrind and scrape to meet requirements.

8、Moving cone sudden acceleration causes: moving cone sinking or spherical thrust bearing damage; The movement of the conical bushing causes insufficient clearance between it and the spindle. Solution: Adjust the gap.

9、 drive shaft rotation is not uniform, produce a strong knocking sound after the pulley rotation, moving cone real estate causes: gear wear or damage; The connection key is damaged; The main shaft is broken. Solution: Stop to replace the gear, and make the meshing clearance meet the requirements; Replace the connecting key; Replace spindle and strengthen iron removal work.

10、 The audible splitting sound occurs when the ore is broken or idling. The cause is: the liner is loose; Moving or fixed cone liner is not round and produces impact. Solution: Stop the machine to check the fastening of the screw and the loss of the zinc layer.

11 、The coupling rotates after the knocking sound and the crusher real estate causes: the key of the coupling or gear in the transmission part is broken; The main shaft is broken. Solution: disassemble and replace; Demolish and replace.

12、 drive shaft rotation is not uniform, resulting in a strong knocking sound causes: bevel gear installation unqualified, meshing poor, excessive clearance, drive shaft axial clearance is too large or the gear is damaged. Solution: Adjust the mesh clearance or replace the gear.

13、 There is a violent impact sound, the supporting ring jumps, and then the normal work causes: non-broken materials fall into the crushing chamber, and it is easy to cause the spindle to break. Solution: Strengthen iron picking or install iron remover.

14、 The reason for the increase of ore particle size: the liner wear is serious. Solution: Adjust the discharge port, reduce the size of the discharge port; Replace the liner.
