The utility model provides an intelligent electromagnetic de -ironing separator for cement manufacture line, it includes cement conveyer belt body, the intelligent electromagnetic de -ironing separator includes metal detector and battery deironing device, and metal detector passes through support fixed mounting in cement conveyer belt body top, and battery deironing device includes hanging assembly and electromagnet assembly, hanging assembly includes support, height -adjusting bolts, a set of wire rope, casing and a set of rings, and height -adjusting bolts's one end is connected on the support, structural design is reasonable, easy operation, and metal strain gauge can change its position on the pole is adjusted to the metal, the further number of turns that changes access electric magnetic iron remover's solenoid according to the signal power that metal detector detected to adjustment de -ironing separator effective power has avoided the operation of the long -term full power of de -ironing separator, reaches energy -conserving purpose. It is undetected when the signal as metal detector, metal strain gauge rigidity, coil turns is fixed, and electric magnetic iron remover power is enough to keep original iron plate not fall down can.
