After the installation of the plastic crusher, the fasteners of all parts should be checked and tightened if they are loose. At the same time to check the belt tightness is appropriate.

3. Before starting the plastic crusher, first rotate the rotor by hand to check whether the jaw, hammer and rotor are flexible and reliable, whether there is collision in the crushing room, whether the rotating direction of the rotor is consistent with the direction indicated by the arrow of the machine, and whether the lubrication of the power machine and plastic crusher is good.

4, do not casually replace the belt pulley, in case the speed is too high resulting in the explosion of the crushing chamber, or the speed is too low affecting the working efficiency of the crusher.

5. After starting the plastic crusher, it should be kept idling for 2~3min, and then feeding after there is no abnormal phenomenon.

6, the work should always pay attention to the operation of the plastic crusher, first of all, the feeding should be uniform, to prevent blocking the crushing chamber; Second, don’t overwork for a long time.
