Disk metal detector is a specialized device designed to identify and separate metallic contaminants from bulk materials in industries like food processing, pharmaceuticals, and recycling. It features a rotating disk or conveyor system that transports products through a detection zone where a magnetic or electromagnetic field senses metal particles.

Key components include a search coil (generating the detection field), a control unit (analyzing signals), and an automatic rejection system (removing contaminated items). These detectors excel at finding ferrous, non-ferrous, and stainless-steel contaminants, even in challenging environments.

Advantages include high sensitivity, minimal false alarms, and compliance with safety standards (e.g., HACCP, FDA). They ensure product purity, protect machinery, and prevent consumer hazards. Modern versions offer user-friendly interfaces, adjustable settings, and integration with production lines.

Applications span food (powders, liquids), textiles, plastics, and mining. Regular calibration maintains accuracy. Disk metal detectors are vital for quality control, enhancing efficiency and safety in industrial processes.
