Magnetic Separators are specifically designed for the continuous
separation of ferrous content from material carried by conveyor
belts or vibratory feeders. The machine consists of a stationary
magnet around which a belt traverses, automatically cleaning the
magnet continuously aryd keeping it at peak efficiency. The overband
separator is mounted over the conveyor either in a transverse position,
discharging extracted iron into a receptacle at the side of the
conveyor, or it can be supplied for operation in-line with the main
conveyor, being positioned over the terminal head pulley and discharging
extracted iron forward of the clean material trajectory. This is
shown diagrammatically overleaf.
separators are designed to operate at a predetermined working gap
over the material bed on the conveyor, always providing the same
flux density at that gap ensuring high extraction rates. In addition
with the advent of high power ferritic magnets, an extensive range
of permanent non-electric overband separators is available to provide
similar units to the electro equivalent in all the lower ranges
of operating gaps.Common applications for the use of overband separators
exist in the removal of tramp iron from foundry sand, sized coal,
stone, glass cullet, fertilizers, crumb rubber, household refuse
and similar materials. Applications also include the removal of
tramp iron to protect crushers,shredders, and similar expensive
and vital processing equipment.
Magnet Unit--Tripolar design with core, poles, and backbar
in high permeability mild steel. The base fitted with a robust stainless
steel rubbing plate designed to withstand heavy impact of extracted
tramp iron.The energising coil wound in high conductivity aluminium
is heavily insulated and connected into a terminal box to receive
Permanent magnetic overband units are constructed in similar fashion
to the electro but have a fully stabilised non-deteriorating strontium
ferritic magnetic core.
Rigid welded construction in rolled steel channel of ample
size to support the total weight of the unit.

from mild steel with crowned face to assist belt tracking and mounted
on bright steel shafting.
Of rubber/neoprene with nylon and terylene plies, selected
because of its excellent properties to withstand impact loads and
give long life. The belt is jointed with non-magnetic fasteners
and fitted with attractors.
