GR2 Series
GR2 Series Film Grinders
AEC’s exclusive GR2 film grinders use dual cutting chambers to reduce the fluff to a smaller particle size, providing a higher bulk density, which results in higher re-feed rates. Scrap film first passes through a primary upper cutting chamber, then through a secondary lower chamber with a smaller screen. GR2 grinders are excellent for tacky, heat-sensitive materials, like LLDPE and PVC. GR2 Series grinder design permits a very high line speed edge trim, because the top chamber stays evacuated to enable efficient ingestion of materials. Excellent for high-speed cast film lines.
REQUEST A QUOTE Find a rep- Higher bulk density makes ground film fluff more suitable for re-feeding into the production process. The GR2 Series uses two-stage grinding to create smaller particle sizes and higher bulk-density fluff, which allows for higher re-feed rates.
- Two-stage grinding passes film scrap through a primary cutting chamber and then through a secondary chamber with a smaller screen. This further reduces the fluff particle size and increases its bulk density for downstream reuse.
- Tacky and heat-sensitive films can require specialized grinding equipment to process effectively. The GR2 Series is specifically designed for materials such as LLDPE and PVC, making it suitable for film applications with these characteristics.
- Reducing film scrap into smaller, higher-density fluff makes more material available for re-feeding into the production process. The GR2 Series is designed specifically to produce higher bulk-density fluff that supports higher re-feed rates.
- The GR2 design keeps the upper cutting chamber evacuated to support efficient material ingestion, allowing it to handle very high line-speed edge trim applications. This makes the system particularly suitable for high-speed cast film lines.
- Key considerations include the type of film being processed, desired fluff particle size and bulk density, required re-feed rate, production line speed, and how scrap will be fed into and removed from the grinding system.
