Gravitational Inertial Classifier - how it works

The feed material and primary air enter the top of the unit and travel downward. The air makes a 120 change in direction.  It then exits through the vanes carrying fine particles with it. The coarse particles that are too heavy to make the turn fall to the bottom of the unit where they pass through the secondary air before they are discharged through a valve. Secondary air, entering below the vanes, passes through the curtain of falling particles. Those particles that are near the cut point in size are diverted by the secondary air stream into an eddy current within the heart-shaped chamber. Some fines are captured as they enter the unit while others are drawn from the eddy current. These particles are carried by the exiting air to a fabric filter for final recovery.
