The Permanent Over Band Magnetic Separators (OBMS)
Supension Type Permanent Over Band Magnetic Separator are develioped to remove tramp metal from the product carried by vibratory feeders, belt, or inclined planes. These are mainly used to safeguard machine such as shedders, Crushers, others and to remove ferrous particles and purify the end products (Industries such as coal Mines , Foundries, Cement Works, food, Sponge Iron< Glass, Char Coal, Chemical and Domestic waste recycling Plants)
These Permanent Over band Magnetic Separatora are used for an automatic removal of ferrous contamination. For other purposes, fixed permanent Suspension Type Magnets are more suitable.
Several types of separators are developed to operate at pre
determined working space over the conveyor i.e.
100,150,200,250 and 300 mm. while choosing the over band,
the speed of the belt, the nature of the product, its
density, its granulometry and size of the particles, which
have to be extracted are the main parmameters to be taken
2 "U" Section pieces are fitted on the magnet by
fastening ears and are supporting bearings of drums and the
drumd are enuipped with shafts mounted on removable hubs.
All the bearings are equipped with stakes for tightening the
belt. reduction gear coupled Electric Motor/Geared Motors by
vee belts drives the belt.
Magnet Unit :
This Magnet is developed from high Intensity Stroncium
Ferrite Rare Earth Magnets and guaranteed to give full
magnetic power in the entire life span of installation. One
Non Magnetic Stainless Steel Plate is supplied to cover the
poles of the magnet. No need for electrical supply or
These Magnetic separator can be installed either inline over
the terminal head pulley (Image-1) or transversal to the
Conveyor (Image-2). For both cases, it is required to
foresee Non-magnetic products under the magnetic fileld.
Most suitable position is inline (photo-1) over the head
pulley. The material being conveyed is in vitual suspension
and tramp iron is therefore more readily extracted. Good
results are obtained by combining a permanent Megnetic over
and with permanent Magnetic pulley at discharge end.
