Brief Description of Grain Cleaning & Milling System:
The chain conveyor (at discharge of grain silos) feeds the material to bucket elevator which in turn feeds the material to the flow balancer. The flow balancer feeds classifiers. The classifiers are provided for size separation and cleaning of grain with the help of vibrations produced by 2 nos. of vibromotors. Classifiers are provided with 2-deck system and coarse discharge for oversize material, fines discharge for undersize material and product discharge for good product. Aspiration system is provided for all the classifiers.
The product is passed on to Destoner, it separates stones present in the grain this results in safeguarding the process / upstream equipments. The vibrations produced by two numbers of vibromotors effect stone separation.
Each destoner is provided with separate aspiration system.A magnet is provided after destoners to entrap ferrous particles. Material is then fed to bucket elevator. Bucket elevator feeds grain to the hammer mills. Dedusting points are provided at bucket elevator, flow balancer and hopper above mill.
A dust extraction system is provided for this section. Screw conveyor provided at discharge of mills feed flour to turbo sifter, it is provided for size separation of flour. The oversize particles are recycled & the good product is conveyed to bucket elevator. Bucket elevator feeds flour to flour silos.
