This machine is used for the separation of low density materials from heavy density grains such as wheat, barley corn etc. The grain gets filled from the inlet into the vibro feeder and gets destroyed into the width of air canal.the product is seperated from low density materials in aspiration canal. Clean and heavy density materials get discharged from the machine by the means of finer valves. The air gets recycled by the radial fan to the aspiration canal. The tarar recycles 100 % air, but for that the inlet must be exhausted. The machine must be installed a head or be connected to the central air discharging system.
