The Turbo Classifiers are based on the fact that particle
trajectory in a centrifugal field differs by particle size,
and therefore allows for particle classification down to 0.5
micron. Some of the advantages of the Turbo Classifier are:
It offers a very high degree of accuracy and can handle large
volumes of material. Simple to operate, with microprocessor
controlled operation.
The photo at left is a standard Turbo air classifier.
Below the air classifier, is a schematic of an operating Turbo Air
Classifier, illustrating the path a powder feed takes through the
machine. Coarse particles are acted upon by centrifugal force,
pulling them outward, while finer particles are acted upon by the
drag force (or resistance of air), allowing them to migrate towards
the center of the machine. The unique design of the rotor and
classification chamber take maximum advantage of these effects,
making cuts in the appropriate place to effect fine classification.
Coarse particles discharge on the periphery of the machine, while
fine particles are directed towards the bottom casing for fines
discharge.

The classification particle size cut
may be changed by adjusting the rotor speed and adjusting the
air flow, all accomplished by simple command entering on the
microprocessor keypad on the machine (or remote control panel
for large machines). Since coarse particles are rapidly
discharged, fine particles and mid size particles are
reclassified by auxiliary blades, achieving a high efficiency
in classification.
At right, is a photo of the Lab Size Turbo Classifier,
Model 15MS.
The Model 15 is capable of classification down to 0.5 microns with
coarse classification up to 100 microns. The feed rate is up to
22 pounds per hour. Motor HP ranges from 3-5 HP. The lab unit
weigh’s only 400 lbs. Compressed air of 20 CFM @70 psi is
required for operation of the lab unit.
Other size Turbo Classifiers are available, with capacities up to
16.5 tons per hour.
Dimensions: 37" x 19" x 21"(H) Ship Weight: 650 lbs.
