Conveyor metal detectors from Bunting are engineered to detect ferrous, non-ferrous, stainless steel, and manganese steel contaminants in a wide range of conveyed materials. Available in one-piece (closed coil), two-piece (devisable coil), and under-belt configurations, these systems serve critical roles in food processing, plastics processing, recycling, and heavy-duty bulk handling applications such as aggregate, mining, and minerals. Depending on the setup, detectors can be installed around the conveyor belt or directly beneath the belt to inspect product as it moves through the line.

By detecting metal contamination before it reaches crushers, extruders, packaging machines, or grinders, Bunting conveyor metal detectors help manufacturers avoid equipment damage, product recalls, and costly downtime. When paired with automatic reject mechanisms or used in combination with magnetic separation equipment, they provide a comprehensive metal control solution. Whether protecting a food brand or preventing tramp metal from destroying quarry equipment, these detectors deliver peace of mind, operational efficiency, and long-term cost savings.
