Detailed Product Description
Air Classifier
Operating principle:
Classifier, together with cyclone separator, dedusting filter
and radial fan, forms a closed loop system of classification. Under
the suction force of radial fan, feed materials are brought with
uprising air stream into classifying cavity from feed inlet of
classifier. Under strong centrifugal forces of high-speed rotating
turbo wheels, coarse and fine materials are separated. Coarse
materials, together with some fine materials, lose speed after
bumping against wall and fall to secondary draught. During strong
washing of the secondary drought , coarse and fine materials are
separated once again. Fine materials go up to classifying cavity to
be classified continuously, while coarse materials fall down to
discharging outlet and let out.
Performances and features:
- Suitable for accurate particle classification of dry
micro-products with spherical, needle-like or piece shape and
different densities.
- Particle size adjustable between d97: 2um and d97: 150um.
- Classifying rate can reach 60%-85%. The better the fluidity
is, the higher the classifying efficiency, otherwise it will be
lower.
- Horizontal classifying turbo-wheel, high rotating speed,
accurate top point cutting.
- To connect with ball mill, vibration mill and rolling mill to
form a closed circuit.
- Programmable control system, real-time operation status and
simple operation.
- Running under negative pressure. Dust emission less than
40mg/m3. Noise is lower than 75dB (A) through
silencer.
