Particle sizing is a critical production process. Particle size distribution is significant for quality control, quality assurance and performance testing. Examples of this can include: catalyst on catalytic result; cement curing time and ultimate strength; mineral composition and quality and performance; for coating effect and surface luster for painting applications; for determining medicinal taste, absorption rate and curative effect, etc. Therefore effective particle size distribution control in powder processing is the top priority for quality assurance, public health and safety, reduction of energy consumption and control of product waste. Effective control on particle size distribution in powder processing and application is important for quality improvement, protection of public health, reduction of energy consumption and control of environment pollution.
