In the course of use, the metal shredder has uneven discharge. Through analysis, Shuguang heavy machinery summarized the following reasons. First of all, because the voltage is unstable, it will affect the stability of the motor, resulting in uneven speed, fast and slow and other problems, which will worsen the uneven discharge. When the feed is uneven, it is easy to block and cause the cavity to become clogged. Fully process unfinished materials. In severe cases, many blockages may cause downtime or increase in motor temperature. Secondly, the motor is unstable. When the voltage is stable, following the change of the force endured by the transmission, the fixed point of the motor will be displaced and the base screw will be loosened. Therefore, it is necessary to check whether this part is complete. First, the current professional standards for shredders are not standard, and the supporting shredder blade standards are also complicated. The shredder produced by the same manufactur
