It is made up of concrete, steel and cement. A pit is dig in the soil below the ground level about 2 to 2.5 mtrs. depth. It is covered with a net of 10 mm round steel duly welded with 5 mm round at a particular distance. We can put about 50 bags of 100 Kg. weight in this pit at a time.
There is a controlled mechanical system for opening the gate of Intake Hopper to Ist Elevator. Ist single Bucket Elevator lifts the material vertically and feeds it in Drum Sieve machine. It is a rotary drum type sieving machine which can separate out the fine dust by aspiration system developed by (-)ve pressure and thrash, jute sutli, lumps etc. will be separated out by sieving.
After sieving through the Drum Sieve, the material will feed in vibro type Seed Cleaner by gravity. The impurities which are bigger or smaller than the size of seed, will be separated out by sieving with the help of different size sieves and the light impurities will be separated out by Aspiration System. These light impurities will be collected in the Dust Cyclone.
After sieving the material from Seed Cleaner, the material will go into the 2nd single Bucket Elevator by gravity. This Elevator will lift the material vertically and feed it in the Worm Conveyor which is fitted on the top of Ist & IInd Concrete Bins. The cleaned material will go into Ist & IInd Bins. These bins are designed for multiple hopper from the bottom side. The output flow of the material can be controlled with variable pocket feeder and the material can be put in the Worm Conveyor. The Worm Conveyor takes the material from Ist & IInd Bins to feed it to Elevator No. 3 by gravity.
