Abstract: For the process of crushing in mines,in order to prevent metal from entering the equipment and causing damage to it,the iron remover is used to remove the metal.The current methods of iron removal in mines and existing problems are discussed,and the future development direction of iron separators is prospected.At present,non-magnetic mines mainly remove iron by iron remover,and then detect by metal detectors.If metal is not removed,the machine will be shut down manually.The magnetic ore is mainly detected by metal detectors,and the electromagnetic iron remover ex-magnetizes and removes iron.This method has many problems in mine application of which with high iron removal requirements.At present,some magnetic mines have been improved,using metal detector+electric three.Although the above iron removal method is widely used in mines,there are various disadvantages.In the future,new intelligent high-difference iron removal equipment and new principle iron removal equipment should be developed to meet various complex conditions of iron removal.
