Gravity Fall Metal Detectors
Gravity free fall metal detectors are precision-engineered systems designed to detect and remove both ferrous and non-ferrous metal contaminants from free-falling bulk materials such as powders, granules, and grains. These systems operate by inspecting product flow as it falls freely under gravity through a metal detector coil, instantly rejecting contaminated material using a fast-acting separation flap or diverter valve.
Detect: Detect ferrous, non-ferrous, and stainless steel contaminants
Protect: Protect downstream equipment from metal damage
Maintain: Maintain production efficiency with minimal interruptions

About
Bunting’s Free Fall Metal Detectors are precision-engineered solutions designed to detect and remove metal contaminants from free-flowing bulk materials such as powders, granules, and flakes. These systems are essential for maintaining product purity, protecting machinery, and ensuring compliance with quality standards across industries like food processing, plastics manufacturing, and recycling.
Our advanced metal detection technology identifies all types of metals—ferrous, non-ferrous, and stainless steel—within gravity-fed product streams. Once contaminants are detected, our high-speed reject mechanisms swiftly isolate and remove them without interrupting the production process. This ensures minimal product loss and maximized operational efficiency.
Key Benefits for Your Business:
- Protect Product Quality: Deliver contaminant-free products that meet the highest industry standards.
- Safeguard Machinery: Prevent costly downtime by removing harmful debris before it damages equipment.
- Boost Efficiency: Operate without interruptions thanks to automatic detection and rejection systems.
- Reduce Waste: Minimize loss of good material during the rejection process.
Whether you’re safeguarding food ingredients like flour or sugar, ensuring the quality of recycled plastics, or protecting chemical production lines, Bunting’s Free Fall Metal Detectors provide a reliable and cost-effective solution to meet your needs.
