Screen Arrangement :

 

  • TOP SCREEN : Removes oversize material / impurities.
  • MIDDLE SCREEN : Removes one grade of undersize material.
  • BOTTOM SCREEN : Removes second grade of undersize material.

 

Operation :

 

Seed/Grain is fed to the feed hopper which are lifted by aspiration and fall on the top screen by feed spout. During lifting process, the heavier matters like stones, iron pieces etc. are separated and drop on the floor. Before falling on the top screen, seeds/grains are subjected to the primary air aspiration which removes dust, straw, chaff and the other lighter impurities. Grains are then pass through three screen arrangement for separation according to width & thickness. After passing through screen separations, cleaned/graded seeds/grains pass through secondary air aspiration where remaining lighter impurities are separated. Final seed/product and impurities are collected separately through discharge spouts into the bags holded on the bag holders.
