In this process, the particle size that passes through the screen holes is called the undersize product, and the particle size that remains on the screen is called the oversize product. Screening is widely used in many fields. For example, in the food industry, sieving instruments are used to analyze the particle size, shape and distribution of food particles to control the quality and taste of the product. In the pharmaceutical industry, screening is used for particle size analysis and quality control of tablets to ensure the bioavailability and efficacy of drugs.
