Conveyor belt mineral metal detector GJT-IF-6B
For iron ore grade less than70% mixture
Especially for black and nonferrous

Introduction:
Iron ore mixture GJT-F-B mineral metal detector is the latest product in metal detecting field. In circuit design, this product adopts digital phase shifting and related detecting technologies, which are the latest metal detecting technologies. With stable performance, high detecting sensibility and strong disturbance resisting ability, series GJT-B metal detector is widely used for belt conveyors in thermal power, cement, 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.

GJT-B(GJT-1F) metal detector can be applied to coal, mining, timber, cement, chemicals, iron sinter, coke and other industries. Especially for black and nonferrous metal mines.

GJT-B(GJT-1F) metal detectors developed by our company, both can detect magnetic metal and manganese steel. This kind metal detector also can detect harmful metals which mixed iron ore less than grade of 70% .
