To guarantee normal operation of the Impact Crusher and to extend its service life, the user should always maintain it.
After the new of Impact Crusher is operating, check the Impact Crusher when work finishes. About two weeks later, check the Impact Crusher every month. And check wholly the electrical motor and lubrication of the equipments each week. The contents of check should cover the fastening of fixed parts, belt transmission, the seal of bearings, switches of the electrical machine.
Check the main parts such as the hammers, the impact plate, and the liners every week. And establish a system for maintaining and replacing periodically according to the repairing circle.
Adjustment of distance between rotor and the impact plate.
When the rotor is running, the distance between the rotor and the impact plate can’t be adjusted. If the stuff is blocked between the impact plate and the frame, hold up the impact frame slightly before adjusting the distance again, in this way, the stuff will be loose and the impact frame easy to be adjusted. If the holding up of the impact frame isn’t enough, beat the loose pole (to protect with a wooden plate). The distance between the rotor and the impact plate can be finished by the adjustment device. First loosen the screw pole, next move the long screw nut and then the pole will move in the arrowhead direction. When it is adjusted well, fasten tightly the screw pole. The distance size can be observed by opening the repair door of the frame. The user must pay special attention and the above work must be done after stopping the machine in case some accidents happen.
Replacement of the tear and wear parts
When replacing the tear and wear parts, open the back frame first. The Impact Crusher adopt ratchet device. Remove the join screw bolts between the back frame and middle box-frame first, next two persons operate the handles on the ratchet device on two sides at the same time and open the frame slowly. Meanwhile, take advantage of the hanging device above the frame to hang up the back frame. And then move the direction-changeable handle on the ratchet wheel. Repeating the above process, close the back frame.
Assemble and disassemble of locking Assemblies
No-key and locking Assemblies connection is used for fixing of large pulley.
When assemble or disassemble the locking Assemblies, please loose screw in the sequence of cross angles, however please not pull out all the screw. Remove bolt and washer, hit the head of all bolts in order to loose the locking asseblies and pull it out. Clean all relative parts before assemble the locking assemblies, add enough grease. All grease shall not contain molybdenum disulfide additive. Then put locking assemblies between shaft and pulley, fasten locking bolt, push the grooved pulley in right position with tooles. Finally fasten screw in the sequence of cross angles on the circle with torque wrench (1/3 MA, 1/2MA, MA) until all screws reach the given MA. Before using torque wrench, please check MA=125.N.M. Then put anti-rust grease on the outside part of locking assemblies and head of screw.
