Dust is a solid particle that can settle under its own weight but can remain suspended in the air for a certain period of time. Dust explosion refers to the explosion phenomenon that occurs when combustible dust suspended in the air touches open flames or electric sparks and other ignition sources. Combustible dust exists in many industries and fields, such as coal mining, metallurgy, and manufacturing industries, such as textiles, wood processing, mining, grain processing, food production, polymer plastic industry, synthetic dyes and coatings, new detergents, bleaching powder, pesticides, and drug manufacturing, which pose serious dust hazards.

For the same substance, the above parameters are not fixed, but are related to the particle size, moisture content, powder morphology The properties of ignition sources are closely related. Generally speaking, the finer the particle size of dust, the larger its specific surface area, and the higher the degree of danger. Dry dust also has a higher risk. Therefore, when using the above dust risk characteristic parameters, it is necessary to understand the particle size and moisture content of the powder
