An empirical study of a gravitational air classifier
The air–particle mixture leaves the gravitational–inertial classifier at point 7 in Fig. 1.This flow of air and particles then enters the centrifugal classifier (point 8 in Fig. 1).At point 9 in Fig. 1, the momentum of the particles separates the air from the particle flow into two sides of a guiding vane (point 10 in Fig. 1).The air flow passes on the outside, while …
