Since most of the packaging machine is packed with powder and particles, it is inevitable to have dust. The particles are fine, and those ultrafine powder materials (such as milk powder, toner, etc.) are particularly serious. At this time, due to the large amount of material dust floating in the air, most of the flammable and explosive dust with H, C, N, S and other chemical elements, when they occur in the air oxidation reaction, heat generation will have the risk of explosion, especially aluminum powder such as the explosion in the carbon dioxide environment.

Having said that, the difficulty of material dust explosion is related to its own nature and the environment. And the causes of the explosion are not the same, some materials are easy to conduct electricity, and some materials are not conductive but will bring static electricity because of machine operation and air friction.

So how to simply do the packaging machine explosion-proof measures is very necessary, here is a brief introduction to a few points:

1. Ensure the ambient air is stable and avoid exposure to oil mist. Gas and other flammable and explosive environment;

2. The use of dust-proof means such as dust-free feeding station and ensure the tightness of the packaging machine and conveying system to completely eliminate dust, which can avoid explosion with a high probability;

3. The use of explosion-proof motor (explosion-proof type, increased safety type, positive pressure type, non-spark type and dust explosion-proof type, etc.) and explosion-proof touch screen and other explosion-proof equipment assembly manufacturing packaging machine.
