The Air Grader separates the material in the vertical air flow over two sifting stages. Heavy and coarse material is discharged via screw conveyors and downstream arranged rotary valves. The accepted material is conveyed pneumatically to a high efficiency cyclone. There, the material is separated from the air flow and discharged by an air lock.
