Weifang Yuansheng explains the influence of the temperature rise of electromagnetic iron remover on the effect of iron removal:
The magnetic field strength is proportional to the current, while the current is inversely proportional to the resistance, and the resistance of the current coil increases with the increase of temperature. Therefore, with the extension of the current time, the temperature of the current coil continues to rise, and its resistance increases, and the corresponding current will decrease, leading to the weakening of the magnetic field strength until a dynamic balance is reached. Therefore, the good cooling and heat dissipation effect of electromagnet is an important factor to keep its field strength not sharply weakened. To choose good heat dissipation effect in addition to iron, take double dust collector arrangement to use in turn, timely cooling, avoid coal discharge due to electromagnetic iron removal heating and intermittent iron removal.
