Airknives boost efficiency
September 1st 2009 Aluminium scrap processing
company, Alutrade, has
upgraded its can processing
operation to achieve purity
levels of 0.03%. An essential
part of this improvement is
the use of airknives from Air
Control Industries during
the separation of aluminium
from non-conductive
materials.
The ACI airknives are
located below the two eddy
current units: the first where
heavies (waste) are separated
from the shredded cans after
the magnetic removal of
ferrous metals and the second
for final cleaning of
aluminium shreds before
weighing and bailing.
Their purpose is to boost
the flight of the conductive
aluminium as it is ejected by
the electric field created by the
eddy current device (positives
repelling each other) beyond
a separating baffle. This
greater distance of travel
ensures a positive separation
of materials to achieve a
cleaner end product. More articles from Air Control Industries Ltd: |
