Metal Detector

Product Description

The new generation of LJT-B metal detectors are suitable for the fields such as mine, metallurgy, cement, power station, coal, wood, chemical industry, coke, and ferrous and non-ferrous mine with wicked working conditions. LJT-B metal detectors can detect some metal contamination mixed in materials of iron ore, coal, wood, copper ore, aluminum ore and other ores to protect the belt and equipment in following up procedure. Magnetic separator can just remove ferrous metal, but not non-ferrous metal like manganese steel. While LJT-B metal detector can detect metal contamination in the common materials as well as iron ore with grade no higher than 60%, even nonferrous metal like manganese steel. Metal detectors are playing very important roles in protecting crushing equipment, ensuring safe running of the conveyor belt, improving working efficiency, reducing labor intensity and raising automation level.

Working principle

When metal passes the sensor, it forms inductance variation and eddy current, which forms electric impulse signal. Through processing of circuits, the signal is outputted as passive endpoint of the relay with one open and closed respectively.
