The wet drum separator NTS is used to remove very fine magnetisable components from low concentration, low-viscosity liquids. The NTS is intended for use in the metal processing industry and for the treatment of preconcentrates extracted from the STEINERT high gradient magnetic filter HGF. Around 90 % of the grain sizes ranging from 1 µm to 1000 µm can be separated as sludge. Features such as stainless steel housing and powerful neodymium iron boron magnets are standard.

General Princip :

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.

How it Works : 

The liquid flows through a semicircular separating chamber beneath a stainless steel drum gather is a semicircular separating chamber through which the liquid flows. The cylinder consisting of permanent magnetic discs are positioned within the drum to which the magnetizable particles are attracted. By rotating the drum, the filter cake is lifted out of the slurry and the magnetic field.
