GJT Metal Detector

GJT Metal Detector

GJT Metal Detector is a next-generation unit specifically designed for detecting metals in belt conveyor systems. It features advanced digital detection technology, incorporating digital phase-shift detection as well as multi-frequency and multi-channel techniques. The sensor utilizes a split-frame window design with one detachable end, allowing for easy installation without the need to cut the conveyor belt.

This detector is primarily used in belt conveyor systems for the real-time detection of harmful metals within conveyed materials. It is well-suited for industrial sectors that require metal inspection for bulk materials, such as mining, cement production, coal processing, and port operations.

ADVANTAGES

1.High Sensitivity & Wide Detection Range: Capable of detecting various metals, including iron, stainless steel, aluminum, copper, and manganese steel.

2.Stable & Anti-interference: Utilizes digital detection technology with multi-level anti-interference, effectively preventing false alarms.

3.Easy Installation: Features a split-frame window design, allowing for simple installation without the need to cut the conveyor belt.

4.Strong Material Adaptability: Effectively suppresses the "product effect" caused by magnetic minerals, making it highly suitable for industries like coal, mining, and cement.

5.Intelligent Maintenance: Allows for digital sensitivity setting and includes a self-check function, making maintenance convenient and hassle-free.

6.Comprehensive Linkage Control: Equipped with audio-visual alarms and optional adjustable delay devices, supporting both automatic removal and manual extraction.

PRODUCT STRUCTURE

When harmful metals in the material pass through the sensor, the metal detector instantly triggers an alarm and sends a control signal. After being processed by electronic circuitry, the signal activates actuators such as electromagnets and motor switches. This automatically ejects the harmful metal or allows for manual removal.
