Gilson 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.
Sieve stack capacity ranges from six 12in diameter full-height sieves with pan, or up to twenty 8in diameter half-height sieves with pan. Assembled sieve stacks are simply 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. Recommended particle size range is 1in to No. 635 (25mm to 20µm). The totally enclosed cabinet is designed for safe operation and to help confine and control the airborne respirable quartz, silica or crystalline particles in the breathing zone of personnel.
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 at completion of 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. Rugged painted case is dense, impact resistant MDF board and is mounted on a sturdy, powder-coated ASTM A 513 heavy steel tubing stand.
