Conveyor Metal Detector 

A conveyor metal detector is a tunnel-type belt conveyor system designed for detecting and rejecting ferrous and non-ferrous metals from a production line. The system incorporates transmitter coil, which generates and maintains a contact electromagnetic field, and two receiver coils. When a metal contaminant is detected in the product, it interferes with the electromagnetic field, creating a very small electronic signal for the receiver coil. The system is fully automated to allow automatic rejection of detect metal contaminant from the production line to ensure uninterrupted production flow. 

The process of a conveyor metal detect is completely automated to allow manufacturing and production to operate uninterrupted. It works with different separation mechanisms, including reject flaps, swivel arms, retraction belts, air-blast nozzles or pushers. It detects metallic contaminants such as stainless steel and grades, aluminium and other metals. Because it’s a metal detect, it cannot detect plastics, glass, diamonds, bones, paper, pearls or stone.
