1.Adopt special technology to control temperature rising thus to ensure main data IN which determines performance of the iron remover unchanged, add number N of turn of the coil, reduce current density I so as to largely reduce heating of coil and prolong service life of the iron remover.

2.The magnetic field is distributed reasonable, affect depth larger.

3.Safe function better. It can control working state of the device at any time.

4.The driving of iron-removing belt adopts cycloid needle wheel reducer so it has advantages of reliable operation, convenient adjustment and simple maintenance.
