Recycling of XPS Foam Waste with The Plast-Agglomerator, Type PFV

Continuous Production of High Quality, Free Flowing Granules from XPS Waste

Waste is generated during the production and processing of XPS-extruded foamed boards, such as rejected boards, milling shavings or fabrication waste. "Directly recycled“ with the ORIGINAL PALLMANN Plast-Agglomerator-System, type PFV, these rejects can be re-introduced into the production cycle without delay.

Method of Operation

XPS- foam waste, already precut to a size smaller 20 mm, is pneumatically conveyed into the storage bin of the Plast-Agglomerator. The material is plasticized in the Plast-Agglomerator by means of frictional heat, pressed through the holes of a die and cut by knives rotating at the outer circumference of the die. The agglomerated material is pneumatically conveyed into the downstream hot melt granulator where it is cut to final size. The downstream cascade sifter separates the fines from the granules. The fines are re-introduced into the agglomerating process.

The finished granules can be sacked, collected in big-bags or transported into storage bins.

Advantages & Features

bullet

Gentle agglomerating with frictional heat, right below the melting point, therefore minimum thermal stress of the product

bullet

Excellent end product, i.e. free flowing granules with a high bulk density

bullet

High throughput rate

bullet

Fully automatic continuous operation, the system is designed for rough 3-shift operation

bullet

Fully automatic cold start without previously cleaning the agglomerating chamber

bullet

Low space requirement as the system is laid out in modular, compact and space saving design
