s, and straw is the next important func- tion of thresher. The process begins as the grains, chaff, and straw rst leave the concaveopenings. During operation, large portion of threshed grain or seed along with some chaff and straw is separated from the straw by the threshing unit. Rotary separators and oscillatory straw carriers are the common forms of grain separators adopted in all stationary 9 DattaTable 7 Range of CylinderConcave Parameters in Threshers for Cereal and Pulse Crops Peripheral Concave velocity Wrap angle clearance Crop (/) Cylinder conguration Concave conguration degree (mm) Ref.
