GJT-B metal detector machine

GJT-B metal detector machine For Cement Plant and Coal mining industry Belt width 600-2000mm For Conveyor belt

GJT-2F metal detector machine the latest product in metal detecting field. In circuit design, GJT-2F conveyor  belt metal detector adopts digital phase shifting and related detecting technologies, which are the latest metal detecting technologies. GJT-2F conveyor belt metal detector with stable performance, high detecting sensibility and strong disturbance resisting ability.

    GJT-2F conveyor belt metal detector is suitable for various kinds of belt conveying and handling system of non-magnetic materials, and GJT-2F conveyor metal detector can accurately detect out the iron, manganese steel, chrome steel, aluminum, copper and other metallic elements mixed in non-metallic materials. Beside sound and light alarm, the control circuit has electric relay output to complete with magnetic iron separator for automatic iron removal. Also GJT-2F mining  industry conveyor metal detectorcan stops the belt conveyor for manual iron removal. GJT-2F  mining industry conveyor metal detector can effectively prevent metal from going to crushing system and protect the secure operation of the equipment.

    GJT-2F conveyor belt metal detector is widely used for belt conveyors in thermal power, cement, coal,paper, mining, forestry, environment protection, building materials and other industries.

 

Working principle:

When the metal gets into the sensor electromagnetic field, some changing signals are generated, and the metal detector can detect them. Then the metal detector can process the signals with electronic technology and drive the executing device (electromagnet and switches of motor) to remove the harmful metal. Timing function: The electric relay will be delayed released after actuation, and the time will be between 1~10 seconds.Output control: One pair of the connection points of the electric relay are open, while the other pair are closed.
