Sieve Shaker: In the pharmaceutical sector, sieving is the most extensively used technique for particle size analysis. The particles are categorized solely on the basis of their size, with no regard for additional qualities such as density or surface features. Micromesh sieves are used to classify particles with a size range of 5 to 20 m, whereas regular woven wire sieves are used to categorize particles with a size range of 20 to 125 m. Punched plate sieves are used to classify coarse particles (>125 m). Punched plate sieves with circular or rectangular apertures are extensively employed in industrial applications. The sieves can be arranged in a variety of ways.

SEC GRINDING.pdf
Secondary grinding is the second stage of size reduction in mineral processing, where particles are further reduced to between 10 and 150 micrometers. This is typically done using a ball mill, which rotates and uses grinding media to impact and attrit the particles until they reach the desired size. The process may involve closed-circuit grinding, where oversized particles are recycled back to the mill. The main steps are material preparation, feeding to the mill, grinding, classification to separate fine and coarse particles, and product collection. Secondary grinding provides benefits like tighter size control and improved mineral liberation but also has higher costs than primary grinding.
