Aug 01, 2007 During the early 1990s two-roll milling was found to give the best result for flexible PU foam grinding, whilst for rigid PU foams ball mills may yield particle sizes as small as 85 m. One factor that limits the amount of scrapped PU foam that can be recycled by regrinding is the viscosity of the polyol/fine particle mixture that can be handled by the processing equipment.

Foam grinding Grinding is a recycling process, in which foam trimmings are converted into loose flakes(by our HHRG-22/11).These are then ground into a powder through shear action in a roller mill. Larger particles are filtered and then fed to the mill until all particles fall into the specified 0.2 mm fines fraction. nanoclays with the part A of the PU material. 3 roll-mill was used to achieve the homogeneous dispersion of the nanoparticles in the final part A mixture. In the present study the distance between the rollers of the 3 roll-mill variates from 120m to 5m depending on the milling cycle. The sequential gap settings were 120, 40, 10 and 6
