Screen Arrangement :

 

  • TOP SCREEN : Removes oversize material / impurities.
  • MIDDLE SCREEN : Grades the material received through the top screen. The good/desired material passes over and the undersize material passes through this section & fall over the bottom screen.
  • BOTTOM SCREEN : Grades the under size material received through the middle screen. The cleaned under size material passes over and the under size impurities passes through this screen.

 

Operation :

 

Seeds/Grains are fed into the feed hopper, are lifted by aspiration and fall on the top. During lifting process, the heavier matters like stones, iron pieces etc. are separated and drop on the floor. Before falling over the top screen, seeds/grains are subjected to the primary air aspiration which removes dust, straw, chaff and the other lighter impurities. Seed/Grains then pass through three screen arrangement for separation according to width & thickness. After passing over the middle screen, the graded seed/grain is again subjected to second stage air aspiration for removal of deceased grain/seed and left over lighter impurities. The final product (first grade), second grade and impurities are collected separately.
