Description
The NEW MODEL CASTED GRINDER CG500 represents the latest evolution in KGR Engisol’s size-reduction technology, specifically designed to meet the high-throughput demands of modern plastic processing facilities. Unlike traditional fabricated grinders, this “New Model” features a high-density, single-piece cast-iron housing that provides superior structural rigidity and exceptional vibration dampening. This robust construction ensures consistent blade alignment and operational stability, even when processing challenging materials like thick-walled PVC pipe scraps, large injection-molded lumps, or rigid industrial profiles. The redesigned cutting chamber is optimized for efficient airflow, preventing heat build-up and material melting during the granulation process, which is essential for maintaining the quality of your recycled resin. The rotor is engineered for high inertia, coupled with a high-performance motor to ensure efficient torque delivery for tackling tough plastic waste. Furthermore, the CG500 includes an improved screen-access system, allowing for rapid mesh size changes or knife maintenance, significantly reducing downtime between product batches. By integrating the NEW MODEL CASTED GRINDER CG500 into your recycling stream, you are choosing a solution that prioritizes longevity, consistent granulometry, and high energy efficiency, providing a durable foundation for your in-house material recovery and waste management operations.
