Alf Magnetic Drum is also named half magnetic roller which is composed of a revolving round stainless steel cover and a shaft to generate a half disc(180 degree) stationary magnetic field . An automated separating system is formed if the drum is driven by a motor.

Features：
1.Continuous self-cleaning design is suitable for automated production line.
2.Surface material is 304 or 316L stainless steel which is in good corrosion resistance.
3.No electric power required for magnetic field generation.
4.Magnetic strength can be chosen by customer.
Applications：
Half Magnetic Drum is mainly used to remove or sort ferrous fines, tramp iron and other ferro magnetic materials from bulk dry material flow such as iron ore, grain,sand,gravel,plastics,wood,waste, cullet, etc.
