PERMANENT OVERBAND A MAGNET
OVBP
SCOPE
Permanent overband magnets,
OVBPs, may be used on all types of
bulk products, on conveyors, vibrating
lines or chutes. They are intended for :
– protecting the plant against ferromagnetic
parts,
– refining and magnetic sorting of
transported products.
Thin and average layers are processed.
Ferromagnetic parts should be
present in small or average quantities
in the product. They are automatically
removed by a powered belt. OVBPs
are mainly used in :
– recycling industries (car crushers,
wood, glass, plastics, selective sorting
etc.),
– quarries, mines and cement works,
– the food - processing industry.
TECHNICAL SPECIFICATIONS
The magnetic circuit, an Andrin ASP,
consists of :
– a machine-welded steel yoke of high
permeability
– a magnetic body consisting of ferrite
magnets with a high field value.
The unit is locked with synthetic resin
in a non-magnetic box.
The frame, consisting of two U steel
sections, supports :
– the ASP magnet
– two rollers, convex machined, set on
dustproof bearings
– geared motor
– discharge belt, fitted with cross lugs
for extracting the ferromagnetic parts
– belt tensioning system.
The belt speed is specified according
to the characteristics of the product to
be processed and the conveyor speed.
INSTALLATION METHOD
Suspended from chains, cables or
straps, OVBPs are fitted either crossways
where the product unwinds or on
the centreline at the head of the
conveyor or vibrating conveyor.
Only the geared motor set requires
electric power.
SPECIFICATIONS
Performances vary according to
various parameters :
– characteristics of the products to be
processed
– properties of the ferromagnetic parts
to be extracted
– characteristics of the plant.
Four types of ASP are offered according
to the working height :
200, 225, 275, 330 mm.
To help you choose, a questionnaire is
attached in our “Iron Removal” document.
THE ADVANTAGES
Sturdiness, reliability and high performance
are provided by simple design
and maintenance :
– steel bearing cover
– drum shafts fitted on removable hubs
– non-magnetic refuse flap fitted on
the upstream side when fitted crossways
– side safety guards
– original tensioning system, shockproofed.
The equipment is delivered with four
detachable transportation feet.
INSTRUCTIONS FOR USE
The magnetic part requires no maintenance
nor upkeep. Greasing, changing
the belt, drum shafts or geared are
very easy and quick.
