The Important Functions of Sieves Shaker

by Hemant Sharma Digital Marketing Manager

A Sieve Shaker can be hand operated or run using motors powered by electrical energy. The procedure used to assess the particle size distribution of a granular material is termed as a Sieve Analysis.

Types of Sieves

Perforated plate sieves
Woven wire mesh sieves
American standard sieves

The function of the sieves shaker is to expose the particles in a sample to all the openings in each sieve in a stack. A sieve stack forms on fitting each sieve to Sieve Stack for being used in a given particle size analysis into the one above. The sieve that has the largest mesh holes is at the top. Each of the subsequent sieves are of a tighter mesh size than the one that is above it.

A sieve stack might consist of anywhere between 1 and 18 sieves and the number and mesh sizes of the sieves in a sieve stack are dictated by industry/application standards. They might also depend on the stated production standards of specific products.

In concept, the optimal motion of a sieve shaker is circular and vertical. In other words, the sieves shaker undergoes orbital motion. While at first the motion is defined as “rotating the sieve in a person’s hand and tapping it on the side”, the first practical mechanical shakers were made of a rotating orbital table as well as a hammer which imparts, at a fixed interval, a vertical force. This was called the Ro/Tap©, standing for “rotating and tapping”. The name eventually became the copyright of W.S Tyler. The first shakers were very noisy. Developments eventually overcame noise and ended up providing an orbital motion of sufficient violence included.

The effectiveness of any sieve shaker depends upon the characteristics of the material which is being sieve tested. The minimum size to be separated, the resistance to agglomeration as well as the static electric factors Meinzer II Sieve Shaker play a role in the selection of a shaker.

For example, the analysis of dry silica sand is comparatively easy to separate down to 50 microns. While the majority of sieve shakers would do an adequate job on this type of product, if the material has the tendency to clump or agglormerate, a shaker that would give the stack a periodic vertical shock which will end up giving better results. If the material has a high static electricity characteristic methods wet sieving may be needed.

When particles to be separated are smaller than 50 microns, you can make use of other techniques. They may be needed to effectively separate these small particles. Use of ultrasonic agitation techniques often play. Another method involves the use of a vacuum in order to pull small particles via the sieve openings. Such vacuum equipment usually processes through one sieve at a time.

The purpose of sieve shaker is clear is to expose the sample to all the openings in a sieve in a manner which will expedite the passing of particles that are smaller than the openings.
