After manually disassembling the sofa bed mattress, the components are placed onto a chain plate conveyor, which continuously and evenly transports them into a dual-shaft bulky waste shredder for tearing, shearing, and crushing. The shredded materials are then outputted via a discharge belt conveyor, compressed, and packaged for transportation by a transfer truck for final disposal. Suspended above the discharge belt conveyor is a magnetic separator responsible for capturing iron materials, which are then sent to a metal collection box for recycling purposes.
