The process involves feeding EPS foam onto conveyor, which shredding processes. For this purpose, many single shaft or multiple shaft shredders are available for sale, they are small and have great application.
The next step is melting; the shredded foam is fed to a plastic extruder, which exposes the foam to heat, melting the foam and finally solidifies into a continuous form. Similar to shredders, plastic extruder are readily available. A combination of these two equipments gives you in-house recycling ability.
Continuous form processed by the combination of machine can easily be transported to the different destination with great efficiency, as its volume is reduced to fraction of what it had been in.
