The hammer crusher is inserte into the groove of the rotor from the side. And the two ends to be positione with pressure plates, which can prevent axial movement. Because the fastening bolts are remove, the reliability of the plate hammer is improve. The centrifugal force generate by the hammer head rotation and the reaction force during impact crushing are use for fastening and self-locking, and the rotor is easy to be worn and made into a replaceable structural form, so the assembly and disassembly are simple and the production is simple. The metal utilization rate of this method is low, but the improve fastening method uses a slotted hammer with longitudinal grooves on the hammer surface, which greatly reduces the metal consumption rate. The working surface can also be use for four times, and the ground is extend. The service life of the blower is improve.
