Coated Aluminum Scrap Decoating Line (ENV-CAS-4000) | Industrial Equipment | Henan Yushunxin Heavy Industry Technology (ENV)

Machine Working Principle

Engineered for High-Yield Continuous Solid Waste Processing

Architectural aluminum demolition scrap, powder-coated profile off-cuts, and PVDF-painted cladding sheets represent prime aluminum alloys (such as 6063 and 3003) but are heavily contaminated with resilient fluoropolymer and polyurethane coatings. Traditional melting without decoating creates thick corrosive slag, toxic fluorinated fumes, and severe metal loss.

The Coated Aluminum Scrap Decoating Line utilizes a multi-zone continuous thermal kiln operating under inert atmosphere with precise residence time control to cleanly strip cross-linked polymer coatings, delivering furnace-ready scrap with pristine metallic sheen.
