Salient Features :
All steel construction with frame of steel rectangular pipe in one selection welded structure.
Feeding hopper is provided with a feed control gate to regulate the feeding rate & feed roller for uniform and continuous feeding on the entire width of screen.
Specially designed rubber balls are provided to check the clogging of the perforations of screens.
Balls are held in ball trays provided under each screen.
Operation: Seeds/Grains are fed into a feed hopper where they are evenly distributed and drop through a controlled gate on three sieve layers. Before falling on each Screen layer, grains are subjected to primary aspiration which drains off chaff, straw, dust, deceased grains etc.
Material is then passed through sieve sections for separation according to width and thickness. Sieve perforations are kept cleaned by specially designed rubber balls. After passing through screens, cleaned material again passes through air sifter and aspiration where remaining light particles are sucked off by a strong upward draught of air. Final product and impurities are collected separately through discharge chutes.
