[0002] Screening is a method of separating particle groups according to their powder properties such as particle size, specific gravity, charge, and magnetism. The operation of using a perforated screen surface to separate mixed materials of different particle sizes into various particle size levels is called screening. The operation of using a sieve to separate particle groups with a wide particle size range into levels according to particle size or volume is called screening. Screening of adhesive raw materials is a very important step. It can screen out impurities and particles that do not meet the requirements in the raw materials to ensure the quality and performance of the adhesive. In the screening process, suitable screens or screening equipment are usually used to screen according to the particle size requirements of the raw materials.
