永磁除铁器的工作原理
Working principle of permanent magnet iron remover
当颗粒状物料经过永磁自卸除铁器的正下方时，混杂在物料中的铁磁性杂质大约0.1-0.36公斤被吸起，由于除铁器上的皮带不停的运转，当吸附在上面的铁磁性物料经过无磁区时，便被皮带上的铁件刮出，扔进集铁箱，从而达到连续自动除铁的目的。
When the granular material passes under the permanent-magnet self unloading iron remover, the ferromagnetic impurity mixed in the material is about 0.1-0.36kg. Because the belt on the iron remover keeps running, when the ferromagnetic material adsorbed on it passes through the non-magnetic area, it is scraped out by the iron parts on the belt and thrown into the iron collecting box, so as to achieve the purpose of continuous and automatic iron removal.
