The sieving action of SS-8R and SS-12R Sieve Shakers is based on research to obtain sharp, repeatable separations quickly over a broad range of particle sizes and material types. The exclusive action results from perfect circular rotation of the sieve stack and vertical two-way tapping at 48 taps per minute. Circular rotation is superior to inefficient back-and-forth actions that create "dead spots" and prevent complete separation. Particles roll in all directions relative to the pattern of woven sieve mesh. "Up" taps mix, reorient, and redistribute particles to present new orientations to sieve surfaces. "Down" taps assist passing of near-size particles to clear the mesh. These high-capacity shakers can hold as many as twenty sieves, depending on model and sieve frames.
The built-in precision digital controller features push-button start and resets desired test time automatically for exact repeatability up to 59 minutes, 59 seconds. A 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 1/2in (12.6mm) LED display is easy to read.
The integral sieve cover is positioned on two stainless steel guide rods and quickly adjusts to any sieve stack height. The clamping system secures the cover in place and adds vertical pressure from a center knob to prevent movement of the sieve stack. An internal counterbalance system allows the unit to remain stationary during operation without permanent mounting. The unit may easily be moved an again, using the adjustable footpads for leveling. Sieve Shakers are housed in sturdy painted steel cases and powered by 1/3hp electric motors. Sieves and accessories are ordered separately.
