Can the auxiliary materials used in the solid preparation workshop cause dust explosion?

Production and processing sites are often accompanied by dust explosions such as aluminum powder, zinc powder, aluminum grinding powder, various plastic powders, organic synthetic drug intermediates, wheat flour, sugar, sawdust, dyes, bakelite ash, milk powder, tea powder, tobacco powder, coal powder and plant fiber dust.

Dust explosion generally has three situations:

(1) combustible dust is suspended in the air at a proper concentration, forming a dust cloud that people often say; All solid substances in fine powder form are called dust. Dust that can burn and explode is called combustible dust; Dust floating in the air is called suspended dust; Dust falling on the solid wall is called deposited dust.

Explosive dust includes: metals (such as magnesium powder and aluminum powder); Coal; Cereals (such as wheat and starch); Feed (such as blood meal and fish meal); Agricultural and sideline products (such as cotton and tobacco); Forest products (such as paper powder and wood powder); Synthetic materials (such as plastics and dyes).

Dust produced in the production process of some factories and mines, especially in the processing of some organic substances, will cause explosion and combustion accidents under certain conditions.

(2) Sufficient air and oxidant;

(3) There is a fire source or strong vibration and friction.
