Material is screw fed into the cylindrical sifting chamber by means of a feed screw. The rotating paddles which do not contact the stationary screen propel each particle through the screen by the action of centrifugal force. The oversize material is conveyed axially and thrown at the other end. The machine thus separates the material into two grades.
- Complete separation of stones from grains.
- Wide range of applications.
- Counter balanced system for long life & smooth operations.
- Compact in size.
- Low maintenance.
- Dust problem eliminated.
The separation of stone from grains is on the basis of specific gravity of the material. A stream of grain with unwanted stones is fluidized by air flow. The material is fed at the higher end and the clean grain is discharged at the lower end.
The stones having higher specific gravity sink lower and closer to the fine wire mesh deck. The oscillation of deck takes the stones towards the higher side where the stones are discharged. The aspiration system comprises Blower, Cyclone, Rotary Air lock Valve.
