1、 The correct selection of electromagnetic iron remover must also consider the iron content of the material The requirements for iron removal, usage environment, and the characteristics of the iron remover itself should be taken into account when transporting materials with a belt conveyor.
2、 When the material contains a high amount of iron, a self dumping electromagnetic iron remover with continuous iron discharge capacity should be selected. Choosing a self dumping electromagnetic iron remover can effectively protect the belt conveyor from longitudinal tearing.
3、 When the material contains less iron. It is advisable to use manual iron removal electromagnetic iron remover. Lowering the suspension height appropriately is beneficial for tapping. However, using a manual iron remover, when one end of the iron rod is sucked up and tightly held, if the other end is pressed against the conveyor tape, it is prone to longitudinal tearing of the tape.
4、 When the environmental dust (such as coal dust, smoke, mud dust, dust, etc.) is severe. A fully enclosed structure iron remover should be selected.
5、 When the electromagnetic iron remover is installed in the middle (i.e. arranged on the same line), it is advantageous for iron removal due to the forward force of the material and its loose state. The suspension height can be appropriately increased. But the iron components within 800mm of the normal direction of the magnetic pole of the iron remover should be changed to non-magnetic materials.
6、 When the electromagnetic iron remover is installed in the middle (i.e. cross arranged), a non-magnetic linear roller can be added under the tape to improve the iron removal effect.
7、 When the belt speed of the tape conveyor is greater than 2.5m S, the iron remover should usually be installed at the head. If the method of increasing the magnetic field strength is adopted and equipped with non-magnetic rollers, it can also be installed in the middle to achieve good iron removal effect.
8、 In general, the magnetic structure of the iron remover is an open magnetic circuit, and its iron suction has the following characteristics:; Absorbing large, long, easy to small, short; Sharp and easy to ball; Easy to move and quiet. Therefore, for occasions with high requirements for iron removal, the specifications of the iron remover should be appropriately increased or two-stage or three-stage iron removal should be adopted.
9、 When using a multi-stage iron remover The iron removal capacity of the rear stage should be higher than that of the front stage, that is, the magnetic field force (CH) of the rear stage iron remover on the surface of the tape should be greater than the magnetic field force (CH2) on the surface of the front stage tape Otherwise, the iron removal effect of the later stage iron remover is very poor.
10、 When the material contains less iron, using a metal detector in combination with an electromagnetic iron remover (using a short-term working system) can achieve better results.
11、 The suction force of a short-term iron remover is usually greater than that of a long-term iron remover, with lower energy consumption and mechanical wear, and a lower price. The new generation of metal detectors in China has been introduced. Therefore, this iron removal method is worth promoting.
12、 There are various ways to remove iron from magnetic materials, and due to the complexity of the situation, it is advisable to cooperate with manufacturers and conduct joint research in order to achieve satisfactory results.
