Hammer crusher pulley wheels and axle head associated with it, keyway, a situation occurs often wear. When the problem occurs, the use of traditional methods to wheel reaming crusher equipment, repair axis machining after welding head and keyway sizes. However, the high temperature thermal stress generated by welding can not be completely eliminated, in the operation of off-axis prone to broken equipment, causing a major accident. And demolition, welding, machining not only increase labor intensity, but also wasted a lot of valuable production time enterprise. Western countries use more polymer composites for hammer crusher wear-site repair, including the most mature technology is a blessing blue world. Use of polymer materials, free removal, free machining field repair, maintenance costs low, short cycle, greatly reducing the labor intensity of maintenance personnel; it has excellent mechanical properties, superior adhesion, does not produce high-temperature stress broken equipment manufacturers fully meet the requirements of equipment operation. Meanwhile good plasticity, can ensure the shaft and hub mating surfaces 100% contact, to avoid possible gaps again done a good fault repair hammer crusher. The main working parts of hammer crusher rotor with a hammer (also known as hammer) of. Rotor from the spindle, disk, pin and hammer components. The motor drives the rotor rotates at high speed in the crushing cavity. Hammerhead is the main wear parts, hammer crusher direct impact on the efficiency of the crusher. Hammer crusher equipment prices during work, in addition to being hit, but also by the impact of the material, so long-term repeated use, the hammer Face would be destroyed, so that the surface shape changes. Currently the majority of hammer crusher hammer is made of high-manganese steel made. Material from the upper mouth to feed into the machine, hit, impact, shear, abrasive and high-speed movement of the hammer and crushed. In the lower part of the rotor, with sieve, sieve size less than crushed material of grain size is discharged through the sieve, sieve size larger than the coarse fraction retained on the sieve continue to be a hammer blow and grinding, and finally through the sieve from the plane.
