Mainly used in soft materials Chrome Ore Grinding Plant and low abrasive material fine operation. The rotor has movement skills to positive and negative direction, which can greatly improve the hammer use cycle and reduce replacement frequency of hammer head. Common faults and Solutions. Hammer crusher undertakes larger torque or vibration during operation, which often results in transmission failure, common faults are: the wearing in bearing chamber and bearing, abrasion on belt wheel hub, shaft, keyway, etc.

The traditional Protection Device Of Impact Crusher method to repair primarily by welding or brushing, but both them have drawbacks: welding thermal stress by high temperature cannot be completely eliminated, which cause material damage or lead to part appears to bend or break; and brush plating is limited by coating thickness, so it is easy to peel, and above two methods are used in repair metal by metal, cannot change the relations of " hard to hard", will cause wear again under the comprehensive roles.

Such repair method has become less common in western countries. In view of the above problems, Europe, the United States and other countries contemporarily are tend to use polymer composites repair method, the most mature application is 1st line technology products, it has strong adhesion, excellent comprehensive properties, free disassembly and can be repaired on spot. Polymeric materials repair won't make thermal stress influence, and no repair thickness limitation, at the same time, deformability that metal materials do not have can absorb the equipment's shocking and vibration, avoid to wear again possible, and greatly prolongs the service life of the parts of equipment, save a large amount of downtime, creating huge economic value for the enterprise.
