Abstract
An air classifier for classifying a mixture of fine and coarse particles by size or aerodynamic shape, wherein the air classifier generally comprises a settling box through which a laminar airflow passes that improves introduction of particles into the airflow and thus improves separation and grading of particles by the air classifier.
Claims7
A system, comprising:
- a primary crusher breaker for initially crushing material;
- a first screen deck for filtering the crushed material;
- a secondary crusher for receiving and further crushing unfiltered material from the first screen deck;
- a second screen deck for filtering the further crushed material from the secondary crusher;
- a tertiary crusher for receiving and further crushing unfiltered material from the second screen deck;
- a third screen deck for further filtering the filtered material from the first screen deck and second screen deck and the further crushed material from tertiary crusher, and for recirculating unfiltered material from the third screen deck to the tertiary crusher;
- and
- a conveyor for conveying the further filtered material to an air classifier.
