Product Description
The Model GPX.BG Grain Grinder is an industrial-grade machine engineered for precise and repeatable particle size reduction— ideal for official grain inspection, mycotoxin testing, and general cereal and grain processing applications.
The GPX.BG meets requirements for FGIS-compliant grain and mycotoxin sample preparation, delivering uniform grind quality across a wide moisture and hardness range.
Features
- Fast, tool-free cleanout: The entire grinding chamber can be removed and cleaned in minutes by simply loosening three dial plate knobs.
- Low-maintenance operation: With minimal moving parts, the GPX-BG offers reliable performance and easy upkeep.
