PATENTED EDDY CURRENT SEPARATOR SMAR THE PATENT SMAR is a family of patented separators of Non-magnetic (non-ferrous) Metals with reinforced protection. The patent consists of introducing a third roller in the eddy current separator in order to set the winding angle of the belt around the magnet wheel. This design has many advantages : – low retention time of ferrous metals in the zone of induction to eliminate the risk of burning the belt ; – large reduction of radial forces on the magnet wheel enabling the use of thick belts and thin composite shell. The longevity of the bearings is also increased ; – Ideal operation of the belt scraper, placed in front of the third roller. APPLICATION Developed in 1989 for automobile shredder, the SMAR are intended for the automatic sorting of different nonferrous metals in difficult environments (outside, dust, humidity, chemical aggressiveness). The SMAR are thereby classified in incineration units, foundries, floatation, fluff installations, processing of slag, etc. TECHNICAL DESCRIPTION The SMAR consists of : – a thick and flat belt conveyor equipped with double edges for tightness ; – a motorised magnet wheel of large diameter assembled inside an impermeable composite shell ; – a convex and rubber coated motorised roller ; – a third cylindrical roller ; – reinforced element bearings ; – lateral protective covers that are easily removed ; – a separation chute with adjustable flap by lifting screws ; – a mechanical vibrating feeder ; – a single frame housing all of the above parts. SPECIFICATIONS The performance is maximum when the single layer is provided by stabilised products. It varies according to : – the humidity and granulometry of the materials ; – the type and shape of the non-ferrous metals to separate ; – previous iron extraction ; – the flow to process. Six types of SMAR are proposed according to the active width of the belt : 600, 800, 1000, 1200, 1400, 1600 mm. INSTALLATION The SMAR are installed after ferrous separation and screening of the materials. Two lateral galleries are used to reach the bearings, motors and belts for adjustment and maintenance. The electrical cabinet used as a local desk is installed nearby. The endless belt is disassembled from the side opposite the motors. THE EXTRAS The SMAR are designed for high performance with a large flow in difficult environments : – patented Andrin system ; – magnet wheel of large diameter with a maximum of rare earth poles fixed inside a stainless steel hoop ; – 3000 r.p.m. with full safety shell ; – impervious and reinforced composite shell ; – thick belt with double lateral edges that may reach 1600 mm ; NF SEPARATION Réf. : 304 127 03
