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
