A type of agricultural machinery called a thresher or threshing machine separates grain seed from the husks and stalks. To get the seeds to fall out, it beats the plant. The feed hopper, spike-tooth cylinder, concave, oscillating sieves, and blower make up the axial flow type of thresher. On the cylinder, the pegs are set in ten rows. The concave wire mesh sieve opening, measuring 80 x 25 mm, encloses the cylinder.
A machine called a thresher is used to separate grains from harvested crops and produce clean grain with little loss or damage. Grain loss during threshing includes broken, unthreshed, blown, spilled, and so on.
