粒子の大きさ: 材料の粒子の大きさが大きい場合,例えば鉱石の粒子など, a grille permanent magnet iron remover with a strong magnetic field strength and a large spacing between magnetic rods should be selected to allow large-particle materials to pass through smoothly while effectively adsorbing the ferromagnetic impurities in them粉やセメントなど細粒子の材料では,磁性棒の間隔が小さい鉄除去剤を選択して鉄除去効果を向上させることができます.
