Definition - What does Vibrational Sieving mean?
Vibrational sieving is a sieving method used to assess the sizes of granular materials such as gravel. During this procedure, the particles or objects are subjected to three-dimensional shaking movements (usually a circular motion superimposed with a vertical or horizontal motion) over a sieve. These vibrational movements distribute the particles over the sieve while changing their orientation. The particles interact with the sieve mesh, passing through the larger openings as they move around. Like other sieving methods, vibrational sieving is used to separate or measure particles by their size.
Corrosionpedia explains Vibrational Sieving
The size distribution of particles in a granular material plays a significant role in the quality control process in many industrial applications. The construction, food and beverage, and pharmaceutical industries are just some of the sectors affected by the particle size of various materials.
As a result, vibrational sieving is heavily utilized in these industries. One of the main advantages of vibrational sieving (compared to other sieving methods) is its ability to combine various degrees of motion. By subjecting the particle to superimposed circular and vertical movement, the sample is simultaneously spread across the sieve while being thrown into the air. This allows the particles to change orientation, ensuring that all sides of the particle meet the required size criteria.
