The bucket wheel stacker reclaimer  wear phenomenon easily in the process of operation, the traditional solution is to repair machining or welding plating, but both have certain disadvantages: welding and high temperature thermal stress generated can not be completely eliminated, causing material damage, causing components to bend or break; and by brush plating the thickness of the coating, easy peeling, and the above two methods are used to repair the metal metal, can not change the "hard to fit hard", in the comprehensive function of the force, will cause wear again. In contemporary western countries to solve the above problems the repair method of polymer composites, which is widely used in the United States fushilan (1st line) technology, which has strong adhesion, compressive strength and excellent comprehensive performance, can remove free machining. Not only does the welding thermal stress effect, the thickness of repair is not restricted, concession metal products have not have, can absorb shock and vibration equipment, to avoid wear, and greatly prolong the service life of equipment components, enterprises save a lot of time to stop the machine. At present in the country for the bucket wheel stacker reclaimer fault repair, has gradually replaced the traditional way.
