Design and Operation Mode of Zigzag Air Classifier
A ZZ classifier is usually operated at feed rates of 5–15 t/m 2 h . In addition, a solid to air ratio of up to 2 kg/m 3 can still lead to stable separation at a separation efficiency of 0.8 . Air velocity of 2 m/s is industrially considered the lower limit, industrially, whereas 1 m/s is the lower limit of laboratory applications .

Zig zag air classifier
A zig zag air classifier divides a mixed material stream into two homogeneous streams. The upward vacuum extraction ensures the lighter micronized materials blow up to exit the sorting chamber separately, leaving the heavier materials to exit at the bottom. For higher quality performance, B+B builds classifiers by placing multiple units in a ...
Material classification for fine powders | Processing …
Air classifiers can be divided into two types: those that use a classifying wheel and those that do not. For air classification with a classifying wheel, airflow moves against its centrifugal action from the outside of a classifying chamber toward the center. The classifying wheel spins at a high rate of speed on a vertical axis inside the chamber.
