Material is loaded into bunker. Vacuum cleaners, IT-waste, dishwashers, are all put inside. Primary shredding takes place via a 150mm rotorshear, which shreds them into small bits. Contaminants are removed in a picking station. Batteries and other hazardous waste are also removed. The sorted out scrap then pass through an incline belt, and into a secondary shredder (This one has an Acoustic Enclosure). The shredded material that comes out is less than 25-30mm thick. Foils and dust are sorted, too. Then the light fraction is discharged into big bags; the heavy part is conveyed separately. The ferrous fraction is separated via an overband magnet, which gets collected in container. The extraction of the remaining ferrous scrap is done by the neodymium drum magnet. To cut the long story short, the last stage is the Screening station. The purpose of this is to separate material into less than 4mm by screen. The materials are eventually sorted into aluminium, copper, nickel and brass.
