Magnet Position
Position 1 ( In-Line installation)
The preferred installation of a suspended magnet is over the trajectory of the product material where it
discharges from the belt conveyor. This position is referred to as
Position 1, (Figs. 1 and 2). For optimum
separation in Position 1 there must be provision to adjust the location of the magnet in relation to the material
trajectory.

For low feed conveyor belt speeds, typically less
than 100m/min, greater separation efficiency will be
achieved by using a non-magnetic head pulley.
Note: It is preferable if a non-magnetic head
pulley is installed, regardless of the speed of the
conveyor

When installing a self-cleaning unit, examine
the area to ensure there is adequate clearance for the
belt to run and that provision has been made to
collect discharged tramp iron. A hinged
non-
magnetic splitter , adjustable in length, will be
required to prevent extracted tramp from re-entering
the non-magnetics.

At the working suspension height the centreline
of the magnet should be approximately
perpendicular to the trajectory of the material and
General
When unpacking, take care to avoid damage to the equipment and possible personnel injury - the magnet
assembly is very powerful and permanently charged . Remove loose ferrous material closer than 600 mm to
the magnet box. Spanners and other tools within the vicinity where the equipment is to be installed could
become magnetically induced and be attracted to the magnet box with considerable force. Also, when installing
OP magnets check that the unit is in the correct orientation, with the heavy steel end poles at right angles to the
direction of material flow.
