A sieve shaker automates the agitation of particles for particle separation and sizing distribution for a range of materials to meet quality control and quality assurance requirements. The advantages of shakers include consistency, accuracy, and repeatable separations compared to manual sieve shaking methods for particle sizing. Lastly, shakers save a considerable amount of testing time.

Gilson offers a large selection of shakers with varied sieving motions and opening sieve mesh size compatibility for particle sizing analysis of a wide range of material sizes. Matching the capabilities of a sieve shaker machine to specific characteristics of the sample material saves time and effort while providing repeatable results.
Agitation lifts and reorients material, allowing more opportunities to pass through sieve mesh opening size. Sieving machines provide consistent agitation of samples, improving passage of material, overall consistency, and ensuring reproducible results between tests.
Gilson's laboratory shakers offer various agitation methods to ensure efficient separation of materials with different densities and textures. Selecting the right agitation method can be determined by minimum size to be separated, particle size, wet or dry sieving method, and material characteristics like resistance to agglomeration and static electric factors. Select from various types of agitation methods including circular, tapping, rotary, orbital, vibratory, sonic, or air jet.
Some vibratory and mechanical shakers without cabinet enclosures can be modified for wet sieving. Gilson also carries a wet-sieving vibratory shaker featuring a system for pumping and recycling wash water, along with vacuum systems to increase material throughput which is popular for particle separating coal or coke. Gilson also offers Wet-sieving accessories to supply and drain away wash water from the sieve stack.
Other factors in selecting a shaker include degradation, static attraction, desired sample volume, the noise level during operation, and agglomeration.
Newer-model Gilson shakers are equipped with an easy-to-use clamping system to secure and lock sieves in place. All sieve shakers come with a mechanical or digital timer, except the 8in Wet/Dry Vibrator.
Gilson’s Rotary and Silent Sifter® models, along with the Mary Ann® sifters offer the tapping action. Rotary lab sifters work well for mineral aggregates and other materials from No. 4 to No. 635 (4.75mm to 20μm).
These units work well with most materials ranging in size from No.4 (4.75mm) to No.200 (75μm) and come with a manual or digital timer.
This type of sieve shaker equipment performs well on most materials sized between No. 10 (2mm) and No. 635 (20μm). Available vibratory styles include 3 and 8in models, WS Tyler® Ro-Tap®, and wet-dry units.
A pause function on better quality vibratory shakers offers an effect similar to the tapping feature. Programming a pause into the test cycle causes particles to briefly stop and then reorient themselves when agitation resumes.
Units with this feature alone are adequate for coarser free-flowing materials between No. 4 (4.75mm) and No. 100 (150μm). The addition of a tapping mechanism enhances performance and allows efficient separation over a wider range of materials from 1 or 2in (25 to 50mm) to No. 635 (20μm).
This unit is best used for materials from No. 4 to No. 635 (4.75mm to 20μm). A Basic and Advanced model is available.
