The process of sorting particles into different groups based on their size, density, or other characteristics. It's used in many fields, including agriculture and mineral processing or beneficiation.
Once particle separation is done, the efficiency of the process is measured by the percentage of undersized particles still present in the oversized product.
Efficiency is determined by the degree of perfection of separation of the material into size fractions above or below the aperture size. It is a measure of how much of the feed material should have gone through the holes in the mesh versus how much really did go through the holes or apertures.
Numerous factors have an impact on efficiency and are categorised based on whether they pertain to the material itself or other influences.
Frequency, the most important determinant of efficiency - is the number of times the screen mesh peaks and troughs within a minute.
