Screen Arrangement :

 

  • TOP/MIDDLE SCREEN : Removes oversize impurities/ material from the raw seed/grain.
  • BOTTOM SCREEN : Removes undersize impurities/ material from the seed/grain received through the top/middle screen.

 

Operation :

 

Raw Seed/Grain is fed into the feed hopper and is evenly distributed by a fluted feed roll through a controlled feed gate on the top Screen. Before falling over the top screen, seeds/grains are subjected to the primary air aspiration that separates lighter impurities chaff, straw dust etc. Seed/Grains are then passes through three/two screen separations according to width & thickness. After passing through screen separations, cleaned grains/seeds pass through Secondary air aspiration (in case of double stage air aspirations system) where remaining lighter impurities are separated. Final seed/grain and impurities are collected separately through discharge spouts into the bags holded on the bag holders
