A Sieve Shaker is an essential laboratory instrument used for accurate particle size analysis of soil, aggregates, sand, cement, minerals, chemicals, and other granular materials. It automates the sieving process by providing uniform and controlled motion, ensuring consistent and repeatable test results compared to manual sieving.
In civil engineering laboratories, construction material testing facilities, research institutions, universities, and industrial quality control laboratories, a Sieve Shaker plays a critical role in determining particle size distribution. Accurate grading of materials helps engineers comply with quality standards and produce durable construction materials.
Whether you are testing aggregates for highways, soil for foundation design, or sand for concrete production, a high-quality Sieve Shaker significantly improves testing accuracy while reducing operator effort.
What is a Sieve Shaker?
A Sieve Shaker is a mechanical laboratory device designed to hold a stack of standard Test Sieves and produce controlled vibration and gyratory motion. This movement separates particles according to their size, allowing laboratories to perform accurate sieve analysis efficiently.
Unlike manual sieving, a Sieve Shaker provides uniform movement across the entire sieve surface, reducing human error and improving repeatability.
Working Principle of a Sieve Shaker
The Sieve Shaker operates using a ¼ HP motor connected to a precision reduction gear mechanism. Instead of rotating continuously, the sieve table remains inclined from the vertical axis while the direction of inclination gradually shifts in a clockwise direction.
During operation, the table performs both gyratory motion and vertical vibrations at approximately 270 vibrations per minute. This dual-action movement allows the sample to spread evenly across the sieve mesh, ensuring that every part of the sieve surface is effectively utilized.
The gear mechanism runs in an oil bath, which minimizes friction, reduces wear, lowers operating noise, and increases the service life of the equipment.
