Electric motor recycling machines are specialised equipment designed to dismantle and crush scrap motor rotors and extract copper wire (including rotor crushers, rotor copper stripping machines, etc.). Frequently asked questions and answers regarding electric motor recycling machines:

1. Material jamming or machine shutdown

The hardness of motor rotors varies depending on the type of motor. If the feed rate is too fast, foreign objects (such as iron parts or screws) may become mixed in. It is therefore necessary to shut down the machine to clear the blockage, adjust the feed rate, and improve sorting at the feed end.

2. Excessive wear of cutting tools/hammer heads

This may be caused by rotors containing high-hardness silicon steel or by the machine being operated beyond its capacity. It is therefore necessary to use wear-resistant alloy tools, rotate and sharpen them regularly, and control the feed rate per cycle.

3. Bearing damage

This may result from an unbalanced motor rotor, loose foundations or insufficient lubrication. Regular balance checks and tightening of the anchor bolts are required, along with regular replenishment of high-temperature lubricating oil.

4. Excessive dust/noise levels

This may be caused by poor sealing or the absence of an exhaust dust extraction system. A bag filter or water mist dust suppression system must be installed. A soundproof enclosure should also be fitted to ensure compliance with environmental protection requirements.
