Hydraulic cone crusher operation and inspection Notes

 

(1) Check lubrication station and hydraulic station.

　　⑵ check the drive shaft box oil pressure, normal oil temperature rated adjustment in the 450C value of 2 bar (29 PSI), the range of 0.8 to 4 bar (12 ~ 60PSI).

　　⑶ check to the oil and return oil temperature, oil return to the oil temperature rise 50C or so is normal. When the temperature of the oil return to 540 will alarm; back to the oil temperature reaches 570 will automatically stop the feed, and an alarm may not exceed the maximum can not exceed 600C, back to the oil temperature exceeds 600C, the main motor of the crusher will be closed.

　　⑷ check the oil filter cartridge and filter pressure reaches 172kPa, filter dirty alarm will appear and you should replace the filter; filter pressure reaches 276 kPa, filter clogging to occur; if the filter differential pressure lower than 14kPa, the damage to the filter alarm will occur; filter blockage or damage to the alarm, crushing machine will automatically stop feeding, idling 30 seconds, the host automatically stop.

　　⑸ check the hydraulic station button box light is normal, all the red in the normal operation of equipment is off.

　　⑹ observe the drive power and the crushing chamber, the feed material level, to ensure that the fragmentation function packed to the mine, high efficiency operation at full capacity.

　　⑺ check the tight side of the discharge opening, so check it daily discharge at one time, the particle size can be observed nesting or automatic calibration of the discharge opening to check the discharge opening; check the distribution of feed, to avoid uneven feeding, resulting in discontinuity, the cause of the adjustment ring beating. Check the feed particle size and mixed to the gradation is uniform, appropriate to the material particle size, feed particle size is too large to achieve the appropriate discharge opening, and inadequate screening fine particles too much will cause the adjusting ring beating .

　　(8) Check fasteners and fittings are loose.

　　(9) try to avoid the crusher to adjust the ring beating, the adjustment ring beating the main reason for the feed particle size uneven feed particle size is too large, too much feed, the uneven distribution of feed, too wet, the discharge opening too small. The operator must seriously analyze the reasons, the right medicine to solve the problem.

　　(10) Check the pipe leakage.

　　(11) should be checked every 30 days to release the nitrogen cylinder accumulator pressure, every 40 hours should be given the cone and the drive ring cam grease (EP2).

　　(12) Check the liner wear condition, pay attention to the position of the adjustment cap (which determines the value of A size), to determine the exact replacement of the liner time.

　　(13) regular cleaning crusher surface accumulation of ore debris and tank ventilation device.

　　(14) to do the daily work record of the crusher.
