Gilson Sieve Shaker: 8in or 12in Tapping Sieve

Gilson Sieve Shaker: 8in or 12in Tapping Sieve

The 8”/12” Gilson Sieve Shaker with Tapping is designed to get sharp, repeatable separations fast over a wide range of particle sizes and materials. This is critical in quality control to get repeatable results which is essential in many industries. This Gilson Sieve Shaker has unique sieving action, built in digital controller for precision and can hold up to 6 full height 12in aggregate sieves with pan.

Circular Rotation

The exclusive action of this Sieve Shaker is from perfect circular rotation of the sieve stack and vertical two way tapping at 48 taps per minute. The integration of mechanical components like timers and motors makes the equipment perform and accurate separations, automates the particle sizing process to get high level of consistency, precision and reliability. Circular rotation is better than back and forth action which creates “dead spots” and prevents 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 help 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.

Sieve Shaker Digital Controller

The Sieve Shaker built in digital controller has push button start and resets desired test time automatically for exact repeatability across multiple cycles up to 59 minutes, 59 seconds. User selectable modes makes the sieve shaker more versatile, users can customize the operation and settings for better efficiency and accuracy. A pause function allows the cycle to be suspended and resumed with no loss of test time and a 5 second audible alarm sounds at the end of the interval. The controller is easy to program and the large, bright 1/2in (12.6mm) LED display of the digital countdown timer is easy to read.

Functionality for Testing

The Sieve Shaker has an integral sieve cover making it versatile for many laboratory applications. The clamping system holds 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 stay stationary during operation without permanent mounting. The unit can be moved again using the adjustable footpads for leveling. This 12in Sieve Shaker is housed in painted steel cases and powered by 1/3hp electric motors. An enclosed cabinet provides safe and dust free operation and ergonomic advantage for easy rotation and access. Sieves and accessories are sold separately.

Capacity

The 8”/12” Shaker w/Tapping is suitable for many laboratory and testing facilities and can hold up to thirteen half height, ten intermediate height or six full height 12in (305mm) sieves with pan. It is used for particle sizing to get accurate and repeatable results for quality control. 12in sieves have over twice the sieving area of 8in sieves. Recommended sieve size range is 2in (50mm) to No.635 (20µm). Characteristics of individual materials may change the useful particle size range when using the shaker.

The shaker comes with an adapter included to use 8in sieves. With 8” adapter this sieve shaker will hold up to twenty half height or ten full height 8in sieves with pan.
