200mm and 300mm Orbital and Tilting Sieve Shaker

For maximum versatility and accurate separations of 4.75mm to 75µm particle sizes. Extended stack height allows more sieves in a single stack for efficient processing. A simple, orbital tilting action distributes material evenly across sieve mesh. Sieve capacity ranges from 6 x 300mm to 10 x 200mm Diameter Sieves.
