The RES dry electromagnetic iron remover series (models RESD-100/150/200/250/300) provides a magnetic field strength of 0–10000/14000/18000 GS with chamber diameters of 100/150/250/300 mm. It removes magnetic contamination from fine powders such as lithium battery raw materials, alumina, talc, semiconductor-grade quartz sand, silica micro-powder and high-purity wax powder.
