Introduction
Foam recycling is a crucial process for managing waste foam materials such as expanded polystyrene (EPS), commonly used in packaging and cushioning. A foam recycling machine efficiently converts waste foam into reusable raw material, minimizing environmental impact. This article provides an in-depth look at how these machines function and presents solutions offered by Dongshen Company.
How a Foam Recycling Machine Works
Collection and Separation
The first step involves collecting waste foam. The material is sorted to separate contaminants like labels, tape, and adhesives, ensuring purity. Proper separation is vital to maintain the quality of the recycled output.
Shredding Process
After separation, the foam is fed into a shredder. The shredder cuts the foam into smaller pieces, typically ranging from 20mm to 50mm in size. The size reduction facilitates handling and enhances the melting efficiency in subsequent stages.
Melting and Extrusion
The shredded foam is then directed into a melting chamber where it is subjected to temperatures between 120°C and 180°C. This temperature range is optimal for ensuring the foam melts uniformly without degrading. The molten material is extruded through a die under pressure, forming a continuous plastic strand.
Cooling and Pelletizing
The extruded strand is cooled using water or air jet systems to solidify the material. It is then cut into pellets, typically 3mm to 5mm in diameter, which can be used as raw material for producing new plastic products.
