Rotary Sifter

Rotary Sifters offer an improved, reengineered version of a classic design for accurate sieving separations

Design advances, upgraded materials, and quieter, more efficient operation make these units an innovative standout in the industry.

Features:

• Preferred design with some state DOTs
  
• Simple and efficient operation with no clamping required
• Enclosed cabinet controls dust output and nuisance noise
• Powerful 1/4hp continuous duty motors promote smooth operation
• Accepts multiple sieve sizes
• Stainless steel internal drive rods

Sieve stack capacity ranges from six 12in diameter full-height sieves with a pan or up to twenty 8in diameter half-height sieves with the pan. Assembled sieve stacks are placed inside, and the cabinet is rotated back against the stops with no clamping required. An ergonomic side knob allows easy rotation of the cabinet between the loading and testing positions. Two rubber-covered stainless steel drive rollers continuously rotate the sieve stack, and particle separations are assisted by tapping against the stack. The recommended particle size range is 1in—No. 635 (25mm—20µm).

A digital countdown timer with a large LED display precisely times operation up to 99 minutes at ± 1 second. Pause function allows the cycle to be suspended and resumed with no loss of test time, and a five-second audible alarm sounds after the interval. The controller is simple to program, and the large, bright 0.5in (126mm) LED display is easy to read.

Hammer assemblies are 6061 aluminum alloy with Ultra High Molecular Weight (UHMW) Polyethylene heads. The rugged painted case is dense, impact-resistant MDF board and is mounted on a sturdy, powder-coated ASTM A 513 heavy steel tubing stand.
