After the waste battery is put into the feeding hopper, the elevator drives the feeding hopper up in the sealed automatic device. When the feed hopper reaches the top of the hazardous waste crushing building, the feed hopper automatically turns over and pours the batteries into the feed bin of the twin-shaft shredder, at this time, the pushing device will squeeze the materials downward, speed up the crushing speed of the materials and improve the crushing efficiency. Batteries are crushed into small pieces by the shredder, and output through the hopper. In order to ensure the safety of the whole operation, need to be equipped with professional fire-fighting equipment.
