Maintenance of Impact Crusher(二)

On time maintenance of Impact Crusher is very necessary and profitable for the formal operation of Impact Crusher.

Now we will continue introduce the maintenance of Impact Crusher:

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.

Lubrication of Impact Crusher

The user must confirm to the lubricating instruction strictly to make sure the crusher works commonly and efficiently.

Pay attention to and do well the lubrication of the abrasion surface frequently.

Lubricant changes according to the weather condition of the place.

Add grease lubrication in the bearings once for every eight hours’ working. The bearing at two ends of main shaft adopts molybdenum disulfide grease (3# lithium based grease).

Change the lubricating oil once every three months. Before changing the oil, wash the bearings carefully with clean petrol or coal oil. The antifriction grease added to the bearings should be 50～70% of its capacity.

In common situation, the temperature rise of the bearings should not exceed 70 degree. If there is something abnormal, stop the Impact Crusher immediately and find out the reasons.
