1, on-site repair the supporting roller surface wear unevenly, affecting jaw crusher normal swimming jaw crusher operation, the use of temporary installation of the turret and grinding wheel for processing until the mill back to the polished until then adjust the the riding wheel position correction kiln longitudinal centerline.
2, replace the the supporting roller surface badly worn, its thickness to reduce excessive wear of the surface at one end or the middle part of the more serious (Star cone line or concave drum line), a large area on the surface of the supporting roller flaking and cracking care axle neck surface wear scar Supporting Shaft neck badly worn, size is reduced too much or Supporting Shaft neck fracture should stop the kiln processing.
3,Replacement placed between the tire and hydraulic jacks curved skids to prevent damage to the wheels with good riding wheel group size (such as riding wheel center distance riding wheel center to be measured before the demolition riding wheel the size of the supporting roller diameter, roller centerline skew) and make the necessary tags, use of lifting equipment, the old riding wheel hanging out, remove the old bush and replaced with a good bush. Riding wheel replacement, must be installed on the same bearing the same two riding wheel diameter.
4,Replacement repair if repair riding wheel surface and journal size, allowing eliminate defects by means of the method of cutting, riding wheel on the lathe repair. If the surface of the supporting roller large area of peeling surfacing method can be used to repair turning operations should be carried out after the surfacing. Riding wheel surface cracks, crack both ends of the drill ended hiatus planing to crack around metal repair with patching method, should also be undone after welding and machining.
5,Supporting Shaft injury, roller and axle with the gap is too large, when the the prop axle neck diameter size wear exceeds the limit, it is best to use brush plating method, saving time and saving maintenance costs, reduce labor intensity, replacement prop axle, hydraulic jacks to prop the axle pressure from the the prop round hole in, or cut off the journal, and cut off the shaft hole riding wheel car with a lathe, and then hot charging method, the new shaft into riding wheel hole . I introduced a new equipment: stone crushing production line, effectively improve work efficiency, energy saving and environmental protection while at the same time has also been recognized by our customers.
