MAINTENANCE OF VSI5X VERTICAL SHAFT IMPACT CRUSHER
1.Specialized person should responsible for the equipment during the machine running. The operator
should be technically trained with full knowledge of the machine, and should also familiar with
operation rules.
2.In order to ensure normal work of the machine, the safe operation system of equipment maintenance
should be formulated to guarantee the long-term, safe and reliable operation. Meanwhile, the necessary
maintenance tools, spare parts and lubricating oil must be provided.
3.The fastener should be checked during each shift, if finding any part loosened, fasten it
timely.
4.The equipment should be checked periodically through checking door to inspect every inner worn parts
such as rings, liners, guard plate around and wear-resistant parts in the flow passage of throwing
wheel. If found any parts worn, should be repaired or changed immediately. If the wear-resistant parts
is worn, the whole set of them should be changed to ensure the throw wheel in balance. If the throw
wheel found worn, it should be repaired or changed.
5.The fastening parts of throwing wheel should be checked every 7 days, if found any parts worn, replace
or repair them at once.
6.The fastening parts and tear-wear parts of vortex cavity should be checked once half a month. If
anything abnormal, eliminate immediately.
7.Oil lubrication is 32#(Minimum temperature lower than 15℃) or 46#(Minimum temperature higher than 15℃)
antiwear hydraulic oil 150-190L. The first 1000 hour working makes the oil change. Afterwards, 2500-3000
hours change the oil in regular working. The pipes should be disassembled when replacing the oil, the
connecting oil pipes should be cleaned and dry, and worn seal pad should be replaced.
8.Adjust the tensile force of transmitting V belt appropriately, so that to guarantee the V belt is
under even stress. The unbalanced current of the motors in two sides should not exceed 15A. 9.Check
lubrication pressure system frequently, and anything abnormal should be repaired at once.
10.The calcium-based grease should be filled in the seal ring under the bearing cabinet with
cover-rotating type oil cup installed under the bearing barrel when stopping the machine.
11.The bearing barrel should be disassembled and cleaned after 1000 hours of normal operation for the
first time. Afterwards, 2500-3000 hours change the oil in regular working.
