ادامه مطلبA magnetic separator is made up of a powerful magnet that is either placed or suspended from a ceiling or device. If a tabletop magnetic separator is used, materials or mixtures can simply be passed over it. On the other hand, suspended magnetic separators are often hung over the mixture or material to remove magnetically susceptible impurities ...
