Due to the fact that the packaging machine mostly packs powders and particles, it inevitably carries dust. The particles are not bad, and those ultrafine powder materials (such as milk powder, carbon powder, etc.) have particularly serious dust emissions. At this time, due to a large amount of material dust floating in the air, most of the flammable and explosive dust contains chemical elements such as H, C, N, and S. When they undergo oxidation and decomposition in the air, the heat generated poses a risk of explosion, especially aluminum powder, which is prone to explosion in carbon dioxide environments.

That said, the difficulty of dust explosion of materials is related to their own properties and the environment. and the reasons for the explosion are also different. Some materials are easily conductive, while others, although not conductive, may carry static electricity due to machine operation and air friction.
