Particle size analysis , particle size measurement, or simple particle size is the collective name of a technical procedure, or laboratory technique that determines the size range, and/or average, or average size of the particles in a powdered sample or liquid.
Particle size analysis is part of particle science, and its determination is generally performed in particle technology laboratories.
Particle size measurement is usually accomplished by a device called Particle Size Analyzers (PSA) based on different technologies, such as high definition image processing, Brown motion analysis, particle gravity precipitation and light scattering (Rayleigh and Mie scattering) of particles.
Particle size can be very important in a number of industries including chemical, food, mining, forestry, agriculture, nutrition, pharmaceutical, energy, and aggregate industries.

Chemical Industry
There are a large number of methods for particle size determination, and it is important to state initially that these different methods are not expected to produce identical results: the particle size depends on the method used for its measurement, and it is important to select the method for its determination relevant to its use.

Mine
The size of the material processed in operation is very important. Material that is too large to carry will cause equipment damage and slow production. Particle size analysis also helps the effectiveness of SAG Mills when destroying material.
Agriculture
Soil gradation affects the ability to retain water and nutrients and drainage. For sand-based soils, particle size can be a dominant characteristic that affects the appearance of the soil and hence the plant
Particle size analysis in the agricultural industry is very important because undesirable materials will pollute the product if it is not detected. By having an auto particle size analyzer, the company can monitor the process closely.
Forestry
Wood particles used to create different types of products depend on particle size analysis to maintain high quality standards. That way, companies reduce waste and become more productive.
Aggregates
Having precisely sized particles allows aggregate companies to create durable roads and other products.
Biology
Particle size gauges are also used in biology to measure protein aggregation.
