VIBRATORY SEPARATOR The Vibratory Separator features high capacity scalping and screening specifically to remove large and small impurities from cereal grains. We offer this design in six degree and twelve degree slopes in either 75 or 100 sq. ft of screen area. Incoming grain is introduced to the top sieve for scalping oversize impurities, the grain and fines pass through the sieve openings to the bottom screen for undersized impurity removal. The cleaned grain is then discharged into an optional aspiration chamber which can be open or closed circuit.
