Pneumatic Metal Detectors / Separators
Bunting’s pneumatic metal detectors and separators detect and remove metal contaminants from materials conveyed through vacuum or pressure lines. They support food-grade and industrial applications, protecting product purity and downstream equipment in uses such as flour, spices, plastic pellets, and regrind.
High-sensitivity detection, self-monitoring, and fast-acting reject systems help these units integrate with new or existing pipelines. Options include hygienic washdown, ATEX-rated configurations, and Clean-in-Place (CIP) systems.
Detecting contamination before it reaches customers helps reduce downtime, product loss, and recall risk while supporting food safety and quality requirements.
Pneumatic Metal Detector / Separator
Applications
Powdered and granular food products transported through pneumatic conveying systems
Materials Handled
Flour, starch, sugar, spices, cocoa powder, milk powder, grains, and other dry bulk ingredients
Benefits
- Delivers the highest detection sensitivity for pneumatic conveying systems
- Advanced diagnostics and self-monitoring for reliable performance and system visibility
