Gilson Rotary Sifters have an advanced classic design with upgraded materials and efficient operation. The innovative design puts the SS-20 model a step above ordinary rotary sifters while maintaining compliance with specification requirements. These quiet, high-quality models are safer to operate and have a longer service life.

Many state departments of transportations prefer the rotary sifter for aggregate gradations. The SS-20 performs accurate particle size testing on construction aggregates and other granular materials in the 1in—No. 635 (25mm—20µm) size range. Gilson Rotary Sifters convert in seconds to accept 8in, 12in, 200mm, or 300mm diameter test sieves with a simple turn of a spring-loaded knob and repositioning of the turntable. Sieve stack capacity ranges from six 12in/300mm diameter full-height sieves with a pan, or up to twenty 8in/200mm diameter half-height sieves with a pan. No clamping is required.

The totally enclosed cabinet is constructed of a high-quality CNC machined MDF board, precisely fitted to confine and control airborne respirable quartz, silica, crystalline particles, and other nuisance dust. The full-width door is attached with heavy-duty commercial grade hinges to permit easy handling of the sieve stack. The cabinet is mounted on a sturdy, powder-coated stand constructed of heavy ASTM A513 steel tubing. Test sieves and drive mechanisms are enclosed by the cabinet for safe operation.

An ergonomically positioned side knob allows for easy tilting of the cabinet between loading and testing positions. A door safety interlock switch stops the sifter if the door is opened during testing and resets the timer. Tapping hammer assemblies are 6061 aluminum alloy with Ultra High Molecular Weight (UHMW) Polyethylene heads. A dependable 1/4hp continuous-duty motor drives the system. Bearing and rod safety covers eliminate exposed moving parts below the cabinet for greater compliance with OSHA regulations.

The digital countdown timer has a large and bright 0.5in (126mm) LED display. It precisely controls operation up to 99 minutes ±1 second for precise repeatability. The timer features a pause function allowing the test cycle to be suspended and resumed with no loss of test time and a one-button operation and settings are saved between test cycles.

Assembled sieve stacks are placed inside the totally enclosed cabinet, and the cabinet is tilted back to the testing position using the ergonomic side knob and press start. The test sieves are continuously rotated by rubber-covered stainless-steel drive rollers and particle separation is aided by mechanical hammers tapping against each sieve. The timer sounds with a 5-second audible alarm at completion.
