This machine is used for seprating low density materials from heavy density grain such as wheat, barley corn etc. The material is filled to vibro feeder from inlet and as regulary dispersed along with of air canal. At horizontal aspiration canal, the product is seperated throught adjustable wall from low density materials.Clean and heavy density materials is discharged from the machine by means of finger valves. Air is revycled by radial fan to aspiration canal. Tarar recycles %100 of the air but fort hat inlet must be exhausted.( Namely machine must be installed a head or connected to central air discharging system.)
