Wet Drum Permanent Magnetic Separator

The liquid flows through a semicircular separating chamber beneath a stainless steel drum to which the magnetisable particles are attracted. The strong, high-gradient magnetic field is created by a cylinder consisting of permanent magnetic discs positioned within the drum. These special permanent magnets generate particularly high field gradients which are necessary for successful separation, as is the need with all magnetic separators.
For recovering magnetic ferrosilicon in dense media plants and iron ores wet drum separators are primarily used. They remove contaminants from the product stream, increasing product purity and plant productivity. In the applications where the product purity is most essential, the wet drum separators can use powerful rare earth magnets which can remove very fine and weak contaminants even from dense materials.
