Self-cleaning above-the-flow chute plate magnets DND-SFX

General principle of the function of magnetic separator DND-SFX

The automatic above-the-flow chute plate magnetic separator is a unique solution for the separation of ferrous particles from dry or semi-liquid materials. This automatic separator is used in above-the-flow chute or belt applications where the ferrous contaminants are captured by powerful permanent magnets and automatically carried away by a stripper plate into the side waste hoppers.

How does above-the-flow chute plate magnet work?

The cleaning intervals of the magnetic plate can be individually preset according to the type of product being cleaned and the contamination degree. The flush face plate magnet with automatic cleaning is equipped with very strong neodymium magnets (NdFeB) allowing for the most efficient separation of magnetic particles.

The basic elements of the automatic above-the-flow chute plate magnetic separator consist of a self-supporting structure with a stripper plate, strong permanent magnets, a stainless steel chute and waste hoppers (for the removed ferromagnetic impurities). The magnetic plate is suspended above the stainless steel chute (or above a conveyor belt where applicable) and magnetic particles contained in the streaming material are continuously attracted to the stripper plate (equipped on the upper side with powerful permanent magnets). The caught magnetic impurities are then - at preset intervals -transported by the stripper plate into the waste hoppers, and the clean material moves on the chute (or on the conveyor) for further processing.

Which way is above-the-flow chute plate magnetic separator cleaned?

The automatic cleaning is carried out by pneumatic cylinders (moving the stripper pan) and managed by a pre-programmed control unit. The compact DIN 1.4301 stainless steel structure provides for a simple and easy installation into the already existing production lines and at the same time guarantees high resistance and a long working life of the whole system.

Further advantages of above-the-flow chute plate magnetic separator

Thanks to the entirely unique design, the self-cleaning above-the-flow chute magnetic separator allows for automatic recovery without production stoppage, i. e., no undesirable shutdowns occur. Another indisputable advantage is the fact that the material being cleaned is in direct contact with neither the magnetic cores nor the stripper plate. Therefore, not even high abrasiveness of the processed material can result into the damage of the magnetic separator or into the threat to operational continuity.

Which industrial branches can the flush face plate magnet be use of in?

That is why the automatic above-the-flow chute plate magnetic separator represents a well-balanced alternative to expensive trunnion magnet separators and rotary trommel screens which are used in particular to clean materials coming out of ball mills (in the course of cement production, ore processing, coal crushing in thermal electric stations, foam glass manufacturing etc.).
