Note : This grader does not need a feeding elevator as the feeding hopper is at low level and feeding of material is through pneumatic, suction.

Operation:

Seeds/Grains are fed into a low level feed hopper where they are sucked up by aspirator fan and drop on the top sieve. Before falling on Top Screen, grains are subjected to primary aspiration which drains off chaff, straw, dust, deceased grains etc. Material is then passed through two sieve layer for separation according to width and thickness. After passing through screens, cleaned/graded material again passes through air sifter and aspiration where remaining light particles are sucked off by a strong upward draught of air. Final product second grade and impurities are collected separately through discharge chutes.
