Cyclonic Ultrafine Classifier0 pages
The Metso Cyclonic Ultrafine Classifier is a hybrid
air cyclone that combines cyclone and classifier
designs to separate very fine particles. This unit
includes our unique inlet scroll which is designed
with a smooth flow elbow to eliminate currents
perpendicular to the main direction of gas flow
that is present in standard conventional rectangular entrance cyclones. This creates a smooth
and uniform flow in this unit which thus leads to
higher efficiencies then conventional cyclones.
In conventional air cyclones, the aim is to remove
as much of the particulate from the airstream as
possible. However the Cyclonic Ultrafine Classifier is designed to allow the finest particles to
be removed in the ascending vortex. This separation is achieved by introducing a reverse airflow
into the specially designed disengaging hopper
that weakens the descending vortex and creates
a stronger entraining force in the ascending vortex that draws the required particles away to the
fines collector. Control of the separation point is
achieved by varying the percentage of reverse
airflow relative to the total air.
The Cyclonic Ultrafine Classifier is designed to
achieve separations in the region of 50μm (#270)
to 10μm (#1250) with a top feedsize of 5mm (#4).
Tonnages for single units are in the region of
0.1tph to 30tph. Above this level, ‘cluster’ systems are available where multiple units are operated in parallel.
The Cyclonic Ultrafine Classifiers are very low
maintenance even on highly abrasive feeds. The
unit contains no moving parts and adjustments
can be made on-line. The range of manufacturing materials available includes abrasion resistant, stainless and mild steels and aluminum. For
abrasive applications, ceramic lining is available
which give exceptional sliding wear resistance.
