Shredding plastics prior to granulation facilitates handling, increases efficiency, and saves the high-speed granulator from wear and damage.
Purgings are loosely formed masses of plastic that have been discharged from plastic processing equipment following a material or color run. Although these materials can be processed for re-use, they are often too large to be processed by granulators alone. Pre-shredding these purgings facilitates granulator feeding and reduces "slamming" (or heavy impact) and its effect on equipment performance and maintenance
Textiles, whether they come in the form of rolled carpets, furniture, mattresses, or cloth, tend to unravel and wrap around the shafts of conventional shredders, causing them to jam. SSI has developed shredding systems that are specifically designed to deal with this inherent problem, cutting textiles into small pieces rather than long strands.
