impurities can create havoc in a Spinning Mill by Damaging
beaters, card wires etc., Generate Spark (Fire)
1. I have installed Magnets
(Magnetic Elbows) in my mill. Is it sufficient?
Magnets covered certainly remove Metal
impurities to some extent. With the advent of Modern High
Speed Blow rooms fitted with Automatic Bale Openers mostly
pressed bales are fed into the process. Here the metals travel
along with the Cotton and mostly enclosed by them.
MAGNETS DO NOT PICK UP
METAL IMPURITIES COVERS INSIDE A BALL OF COTTON. ELECTRONIC
METAL DETECTORS ARE CAPABLE OF DETECTING METAL IMPURITIES
EVEN INSIDE COTTON.
2. How many Metal Detectors
you require in a Blow room line?
One Metal Detection system will give
3. Where it can be located?
It can be located immediately after
the Bale openers.
4. Any Special requirement?
Yes You need a Straight-line piping
distance of 8 meters after the opener. The Metal Detector
should have a safety distance of 1 meter diametrically, around
which there should not be any Metal objects present.
5. How does it work?
Metal detector consists of a detector
and pneumatic diverter fitted with a collection tank. Metal
impurities interrupt electromagnetic field generated inside
the metal detector when cotton flows through them. This signal
is carried to the diverter when flap diverts the cotton into
a collection tank.
