Magnetic Pulley
Introduction
PML Pulleys are permanent magnetic separators
that operate as head pulleys on belt conveyors. These self-cleaning magnets
remove tramp iron and purify materials conveyed in bulk form. These pulleys
offer superior removal of ferrous contamination like nails, spikes, nuts,
bolts, cans, and wire from material conveyor with maintenance free operation.
These are widely used in following industries:
·
Cement
·
Coal
Handling Plant
·
Salt processing
industries
·
Glass
·
Paper
·
Refractory
·
Minerals
(e.g. Bauxite)
Heavy Duty Magnetic Pulleys are generally
used in Cement Industries, Coal Plants, Ceramic industries and other heavy
industries where continuous flow of material is conveyed over conveyor. They
are also used in addition to Suspended Magnets where material burden depth is
more than 4” with big lump size viz. Cement, refractory, coal plants.
Small
size Magnetic Pulley are more effective where material burden depth is very
less with thin layer of material spread over the conveyor viz. Food industry,
tea powder processing plants and fine powder processing industries.
How does it work?
Magnetic Pulleys are widely used
as head pulleys in belt conveyors for continuous automatic removal of damaging
tramp iron from a variety of materials. When material is carried on a conveyor
enters the magnetic field of the pulley, the ferrous particles are attracted to
the belt. They are then held magnetically and carried to the underside of the
pulley to get dislodged from the belt. Iron separation is automatic and
continuous. The cleaned non-magnetic product is discharged normally over the
pulley in vertical drop.
Construction:
The magnetic pulley is made up of magnets placed
inside a Stainless Steel 304/316 drum shell on a shaft. All shafts are made up
of steel and are amply supported to handle the required load. Shafts are
carefully machined from over–size stock to required finished dimensions. The
magnets are enclosed totally inside the stainless steel drum. These are
installed as head pulley in belt conveyor. The self-cleaning magnetic pulleys
are equally effective in the separation of both large and fine particles from
non-ferrous material.
Types:
·
High Intensity
– (Ndfeb Magnet – 4500 gauss)
·
Low
Intensity - ( Ferrite Magnet - 1200 gauss)
