Description
The CG500 FOR LUMPS by KGR Engisol is a specialized heavy-duty size-reduction machine developed to process large, dense, and irregular plastic lumps commonly generated in recycling, extrusion, and molding operations. Plastic lumps present a unique challenge because of their thickness, hardness, and inconsistent geometry, which require a grinder with strong structural integrity and a high-torque cutting system. The CG500 for Lumps is designed with a reinforced casted body and a powerful rotor assembly that delivers the force required to break down these tough materials into manageable granules. Its wide feed opening accommodates oversized material without excessive pre-shredding, reducing handling effort and increasing plant efficiency. The cutting chamber is optimized to minimize heat generation and maintain material integrity during reduction, while the hardened knives and replaceable screen allow the operator to fine-tune the granule size for downstream recycling. The robust frame and bearing arrangement support continuous industrial use, making the machine ideal for plants that need to recover valuable material from startup scrap, rejected extrudate, and consolidation lumps. For manufacturers seeking a dependable solution to large plastic waste recovery, the CG500 FOR LUMPS provides the strength, reliability, and throughput necessary to maintain a smooth recycling workflow.
