ELECTROMAGNETIC EXTRACTOR DRUM
SCOPE
The TEME Electromagnetic Extractor
Drums are usable on any bulk product
above vibrating feeders, conveyor
belts or chutes.
They are recommended for :
– the extraction of ferromagnetic
materials in high concentration ;
– the sorting of heavy and bulky ferromagnetic
materials ;
– the purification of ferromagnetic
materials.
Used mainly on medium-sized layers,
they are perfect for treating heavy, blunt
products with a large granular size.
Thanks to their robustness and tightness,
they are perfect for outside applications
in an aggressive environment such as :
– car crushing installations ;
– incineration plants ;
– slag sorting ;
– selective sorting centers.
TECHNICAL DESCRIPTION
The TEME drums consist of an envelope
rotating around a fixed magnetic circuit.
The main components are :
– a rotating envelope made of thick manganese
steel for a maximum service
life. It is equipped with reinforced
brackets and side aprons made of nonmagnetic
manganese steel ;
– two aluminum side flanges ;
– a magnetic circuit made of high permeability
steel supporting a main pole for the
extraction of ferromagnetic materials, an
auxiliary pole to retain them against the
hoop and an evacuation pole. The
windings are made of an aluminum conductor
with reinforced insulation ;
– a fixed electric box to supply direct current
to the windings ;
– an innovative magnetic circuit orienting
system, consisting of a key and a screw
connecting rod ensuring a low positioning
over time.
A lefthand drive system is offered in kit or
in option.
The bracket shape can be adapted
according to the flow rate, the products
to be treated and the drum rotating
speed.
INSTALLATION MODALITIES
The TEME drums are always stored at the
end of a vibrating feeder or a conveyor belt
in an extraction position. The magnet's
working environment must be nonmagnetic.
Two installation modes are possible :
– mounted on a rigid frame above a
vibrating feeder ;
– assembled on a retractable frame
suspended by chains or stretchers.
The equipment may be completed by :
– side access catwalks to perform operations
on the TEME ;
– side boxes to contain the thrown ferromagnetic
materials.
SPÉCIFICATIONS
Performances vary according to various
parameters :
– characteristics of the products to be
treated ;
– characteristics of the ferromagnetic elements
to be extracted and basic contents ;
– extraction height.
Five TEME types are offered according
to the work height :
250, 300, 350, 400, 550 mm.
ADDED FEATURES
– A drum extremely resistant to shocks
and wear ;
– A magnetic circuit protection against
external particles and moisture ;
– A homogeneous magnetic field over
the usable width ;
– Alternated poles allowing a magnetic
brazing of the products and an extraction
of clean and quality cast iron ;
– A precise orientation of the magnetic circuit
with an anti-vibration blocking system.
USAGE MODE
No special servicing or maintenance is
required except for the lubrication of the
drive chain and the bearings, as well as a
periodic check of the drum.
