Circular Sieve Shakers use a very simple motion on a flat, oscillating plane. Particles are evenly distributed around most of the sieve surfaces, and randomly fall through openings. These units are adequate for coarser free-flowing materials between 2-1/2in and No. 100 (50mm to 150µm).
- Gilson Tapping Sieve Shakers feature exclusive circular rotation action with two-way tapping operating at 48 taps per minute and Gilson’s innovative EZ-Clamp system efficiently secures sieve stacks for accurate, repeatable separations.
- W.S. Tyler® Ro-Tap Sieve® Shakers use a horizontal, circular motion with vertical tapping action in one direction. Ro-Tap Shakers operate at 278 oscillations and 150 taps per minute and ¼ hp electronic motors and timers for repeatable, accurate test results.
- W.S. Tyler® Coarse Sieve Shakers are rugged units for 8in or 12in sieves, portable enough to use in the field.
