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 ;
