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.
Claims5
A method of separating and grading particles using an air classifier, comprising:
- generating a laminar airflow through a settling box in a direction from an open and unobstructed inlet configured for laminar flow to an outlet of the settling box;
- gravity feeding particles of material into the laminar airflow through a material diffuser column leading to the settling box, the column having a deflector oriented such that the particles enter the laminar airflow in the direction of the laminar airflow;
- and
- separating and sorting the particles based on size, weight and shape into a plurality of receptacles spaced between the inlet and the outlet and a filter at the outlet such that at least one of bigger particles and heavier particles are deposited into upstream receptacles and at least one of smaller particles, lighter particles, and flake-shaped particles travel further downstream.
