With the continuous development of modern industry, the amount of materials transported by transport belts is getting larger and larger, the speed of transport belts is getting higher and higher, and the requirements for raw materials are getting higher and higher. Correspondingly, the requirements for the iron removal effect of raw materials are also higher. The higher the price, the market calls for a special iron separator with superior performance.

        The evaluation index of the electromagnetic iron remover is also getting higher and higher. The two major performance indicators of the iron remover are intuitively understood as the magnetic induction intensity of the electromagnetic iron remover and the magnetic field distribution of the electromagnetic iron remover. This value is only related to the structural form of the electromagnetic iron remover. . The magnitude of the magnetic force is proportional to the product of the magnetic induction intensity at that point and the logarithm of the magnetic induction gradient.

        Taking the suspended electromagnetic iron remover as an example, both theory and practice have proved that the magnetic induction strength at the standard erection height of the self-cooling electromagnetic iron remover is 700-800 GS; the magnetic induction strength at the standard erection height of the air-cooled electromagnetic iron remover is 900- 1200GS; the magnetic induction strength at the standard erection height of the oil-cooled electromagnetic iron remover is 1200-1500GS. If the magnetic induction intensity under the standard erection height of the electromagnetic iron remover is to be increased, the cooling method of the electromagnetic iron remover should be updated.
