Dual Cleaners – KDC PLUS

The Kongskilde dual grain cleaner, KDC PLUS, is a combined screen and aspiration cleaner with capacities of up to 80 t/h. Ideal for the pre-cleaning of corn, barley, wheat, rye, peas and beans as well as for grading of malting barley and seed.

The inner screen serves as a scalper, removing all large particles, and the total outer screen area is available for small seeds or fines removal. This is the only machine available with a fully adjustable pitch.

With the vacuum, you actually get 100% aspiration. It conveys/blows its own screenings up to 50 feet (15 meters). Capacities are adjustable.
