Design and options
The upper cascade screen separates larger and elongated impurities; the lower flat screen removes smaller fractions.
Swinging plates slow the grain as it moves. Grain in contact with the screen sifts through faster and clears blocked holes.
Works with the WS cleaner and the WS/K multifunctional cleaner, and with feeding and receiving equipment.
