    Impact crusher efficiency of our friends are obvious, like the human body , like a long time, there will be some big or small issues that we need to help solve it . Here , peak Heave. W teach technicians to give you some impact crusher is often problematic parts repair methods . Preferred , impact crusher maintenance you have to Start from the hammer We start to understand the repair hammer and hammer the selection of materials , and why ?

    Because counterattack crusher hammer is the main consumable parts , the current multi-purpose gig manganese steel, when one side wear, can be used upside down But when the hammer was badly worn on both sides it is difficult to repair , had to replace the hammer. If at this time the shaft hole and hammer shank is not damaged, but will inevitably cause the entire hammer scrap waste. Therefore, the hammer is in use, can not let too much wear and tear on both sides , we should replace him with a high manganese steel alloy or electrode surfacing to improve wear resistance.

    Secondly You have to understand the crusher frame pair cast steel racks are generally not in direct contact with the material , but the chassis side machine side cover plate and is subject to the material between the chisel -type abrasive wear In addition, the rack shaft shaft hole hammer , hammer crusher after long-term work, the hole will be ground into a flat round hole, impact hammer work Fix the rack is carried out with manganese steel surfacing surfacing .

    Before welding , welding rod to dry after welding, the surface should be smooth , symmetrical position rack surfacing weight would be balanced otherwise it will affect the hammer work, This method is simple, the cost is higher, but the wear resistance can be increased more than I times . Hammer shaft bore wear , after annealing after welding drilling re- crossed or the rack plate combination, for buildings with holes , easy to achieve dimensional accuracy requirements.

    The final step is grate repair and lining repaired Impact crusher grate , due to the material impact and friction, wear is relatively fast , and some even bend and break the grate can wear welding pair , repair, should pay attention to the gap between the size of the grate . The grate can crack repair welding , repair to the attention Of the weld surface smooth.

    Bend and break the grate should generally be replaced with new grate . And more for high-manganese steel liner material, liner wear surfacing method can also be repaired In order to save precious manganese steel surfacing , to use the underlying structural steel welding rod , and then manganese steel surfacing electrode surface .

    When the wear layer is thin it can be directly evenly manganese steel surfacing electrode To save welding electrodes and time savings can be intermittent welding liner into strips and mesh , but not too close the gap discontinuity and depopulation , too dense to save limited depopulation not achieve repair.
