See Table 14 for the faults and troubleshooting methods when the cone crusher is working.

Table 14 Common faults and troubleshooting methods of cone crusher

Serial number Fault phenomenon Possible Causes Elimination method
1 Oil pump heating Oil thick or low oil temperature Change oil or warm
2 Oil pump works but low oil pressure 1 oil suction pipe blocked 2 oil pump gear wear 3 pressure gauge is not allowed Cleaning the oil pipe, replacing the oil pump or pressure gauge
3 The normal working pressure of the oil pump indicates normal but no oil return 1 return oil pipe plug 2 return oil pipe slope is small 3 oil viscosity or low temperature Clean the return pipe, increase the slope, change the oil, and warm
4 No oil or oil flow interruption in the oil level indicator, oil pressure drop 1 oil pipe plugging 2 oil temperature is low 3 oil pump is not working properly Clean the tubing system oil heating check repair oil pump
5 Reduced oil return and reduced oil in the fuel tank 1 There is oil leakage under the crusher. 2 rows of oil grooves block oil from leaking out of the seal ring. Stop inspection, eliminate oil leakage, adjust oil supply, clean or deepen oil drain
6 The cooler does not work or has little effect 1 no cooling water or insufficient water supply 2 cooling system blocked Open the water gate, normal water supply, check the water pressure gauge, clean the cooler
7 Return oil temperature is too high (>60 ° C) 1The eccentric bushing friction surface produces harmful friction 2The bearing works abnormally 3The oil groove section is insufficient and blocked Shutdown maintenance oil supply, cooling system friction surface, clean
8 There is oil in the water, there is water in the oil 1The cooling water pressure exceeds the oil pressure. 2 The individual water pipes in the cooler are broken, and the water seeps into the oil. The cooling water pressure was made lower than the oil pressure by 0.5 k/cm. , check if the cooler water pipe joint is leaking
9 The drive shaft rotates unevenly, the sound is not normal, the pulley rotates and the moving cone does not move. 1 Bevel gear tooth installation defect, the axial clearance of the drive shaft is too large during operation and wear or damage 2 pulley or gear key damage 3 unbreakable material causes the shaft to break Stop the gear change, correct the meshing gap and replace the spindle, strengthen the iron removal system
10 The crusher is strongly vibrated and the moving cone speed is increased. 1 There is no oil or unclean between the main shaft and the bushing. 2 The movable cone sinks or the spherical bearing is damaged. 3 The tapered bushing has a small clearance. Stop the inspection to find out the cause of cleaning, refueling repair or replacement adjustment gap
11 Increased bulk broken products Movable cone wear Adjust the small discharge port; replace the bracket
12 Great vibration during work Insufficient spring pressure, more fine particles and sticky materials, uneven feeding, insufficient spring elasticity Press or replace the spring, adjust the feed to the mine
13 Hear the crack when turning The lining (moving, fixed) is slack, the screws or earrings are damaged, and the lining is not tight and impacts. Shutdown inspection repair or replacement
14 Water-free in the water seal Water seal water supply pipe is not normal Stop to find out the cause of the water supply interruption
