W.S. Tyler Ro-Tap Sieve Shakers

Ro-Tap Sieve Shakers generate 278 oscillations and 150 taps per minute as required by some ASTM and other sieving test methods. The horizontal, circular motion and a vertical tapping action assure accurate and consistent particle separating results.

All models feature a powerful 1/4hp motor for performing consistent particle analysis testing. Models have adjustable-plate sieve support and a built-in 99-minute x 0.1-second electronic digital timer. These rugged test sieve shakers are built for heavy-duty use and can be bolted to benchtops for stable operation.

SS-30 8in Ro-Tap® Sieve Shaker holds up to six full-height 8in (203mm) diameter test sieves with full height pan or thirteen half-height sieves with a half-height pan, ISO 200mm sieves can also be used. Recommended for the separation of particle sizes ranging from No. 4—No. 635 (4.75mm—20µm).

SS-31 12in Ro-Tap® Sieve Shaker holds up to four full-height 12in (305mm)diameter test sieves and pan, six intermediate height sieves and pan, or eight half-height sieves and pan. 12in sieves have more than twice the effective sieving area as 8in sieves. Recommended for separations of particle sizes ranging from 1/2in—No. 500 (12.5mm—25µm).

SS-33 8in Ro-Tap® ll Sieve Shaker performs tests on two separate 8in (203mm) diameter test sieve stacks simultaneously with precisely the same action as Ro-Tap® single-stack models. Recommended for separations of particle sizes ranging from No. 4—No. 635 (4.75mm—20µm).
