One of the most common material applications of plastics shredding is the processing of so-called plastic lumps, which are usually generated as a waste product during the extrusion of plastics. The economic potential of this "purge" is enormous. It is expensive to dispose of the unused purge lumps. Recycling offers the possibility of seamlessly reintegrating production scrap into the manufacturing process instead of using new resources.

Thermoplastics are plastics that, unlike thermosets and elastomers, can be formed as often as required - as long as they are not overheated, otherwise they may decompose. Well-known thermoplastics include polypropylene (PP), polycarbonate (PC), polyamide (PA), polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC) and acrylonitrile butadiene styrene (ABS).
WEIMA shredders are engineered to handle highly abrasive materials and can be individually equipped with wear-reducing options. Thanks to the thick-walled machine frame, they operate with exceptional stability and long service life – even when processing tough plastic purgings. This significantly reduces downtime and sustainably lowers maintenance costs.
The V-rotor, specially developed by WEIMA, can be used universally and is made from solid material. Its aggressive material feed with up to two rows of blades guarantees a high throughput with low power requirements. It can be fitted with hardened steel cutting blades in edge lengths of 30 mm and 40 mm. These can be reversed several times when worn, which drastically reduces maintenance costs.
