Will flour explode?

Oh my god... After making bread, cakes, and noodles for so many years, am I using my rope to make noodles for my family? With doubts in mind, I went to find Du Niang. Du Niang told me, "Flour particles have a larger surface area, stronger chemical activity compared to block like substances, a larger contact area with air, and more adsorption of oxygen molecules. Once they encounter flames, sparks, arcs, or appropriate temperatures, they will instantly ignite, and their power is no less than that of bombs.

However, the explosion of flour still requires two conditions to be met, which is that the concentration of flour must reach 9.7g of flour per cubic meter of air, and it must be exposed to an open flame or appropriate temperature. I calculated that the place where this possibility occurred should be in the flour processing factory!

Wait, doesn't ABB have a dust explosion-proof motor?

M2JAX - Empowering a Safer Production Environment

ABB's domestically produced low-voltage explosion-proof motor M2JAX not only has gas explosion-proof certification qualifications, as well as IP65 and IP66 ultra-high protection levels, but also obtained dust explosion-proof certification qualifications at the end of 2017, providing a safer production environment for more users.

(This certificate is applicable to ABB low-voltage dust explosion-proof motors with a center height of 80, 90100112132160180225250250280315355)

The characteristic of a dust explosion-proof motor is that the casing has high sealing, which can reduce or prevent dust from entering the casing. Even if it does, the amount of dust entering will not pose a risk of ignition. When in use, the allowable temperature on the surface of the casing does not exceed the specified temperature group, so it will not cause an explosion of the surrounding explosive dust mixture.

From the perspective of production environment and application industries, flour and various starch processing, metal product processing, graphite production processes, as well as chemical industry, textile industry, port machinery industry and other processing processes are prone to generate dust and pose a risk of dust explosion. The types of dust include aluminum powder, magnesium powder, zinc powder, titanium powder, zirconium powder, coal powder, flour, starch, sugar powder, milk powder, blood powder, fish bone powder, textile fiber powder, wood powder, paper powder, rubber and plastic powder, tobacco, etc.

Recently, ABB M2JAX low-voltage dust explosion-proof motor has been applied to a chemical calcium carbide manufacturer, playing a role as a safety guard in the calcium carbide dust environment.
