After grit is discharged to the Classifier, the grit and water mixture from the grit air lift is discharged over a weir. Settled grit is then removed by the helical screw conveyor, equipped with steel flights. The sectional flights are fabricated with hardened welding on the leading edge for durability and strong-wear resistance.
