Mechanical Tapping Sieve Shakers

Mechanical Tapping Sieve Shakers use a repetitive two-way tapping motion paired with an aggressive circular mechanical action to yield accurate material separations while preventing blinding. These units are ideal for a wide range of materials between 2in (50mm) to as fine as No. 635 (20µm) using 8in to 12in (200mm to 305mm) ASTM or ISO test sieves.
