There are usually two combine sieves, one above the other, or called upper sieve (top sieve) and lower sieve (bottom sieve). The combine sieves are basically a metal frame, that has many rows of "fingers" set reasonably close together. The top is set with more clearance than the bottom as to allow a gradual cleaning action. The angle of the fingers is adjustable as to control the size of material passing through and change the clearance. Setting the fan speed, concave clearance, and sieve size is critical to ensure that the crop is threshed properly, the grain is clean of debris, and that all of the grain entering the machine reaches the grain tank.
