Many solids like wheat dust, wood dust and even metals in their dust form have high surface area. With a high surface area and surrounded by oxygen (as in the air), combustion can take place at a very rapid rate. This rapid rate of combustion can lead to an explosion. In fact, Dust explosions are hazards in many industries. Taffy

Why do extractor fans reduce the possibility of an explosion in a flour mill?
Dry dust in the air can explode. Removing the dust prevents the possibility of an explosion.
What causes a dust explosion?
A dust explosion occurs when a flammable substance in powder form suspended in the air ignites and burns rapidly. When a substance is pulverized, the surface area that is directly exposed to the air increases dramatically. This large surface area allows the combustion reaction to occur much more rapdily than would normally be possible, causing an explosion. Substances that can produce dust explosions include sawdust, grain dust, coal dust, starch, flour, and even some metals.
What is an example of miller in a sentence?
The miller was covered with flour dust. The miller only ground wheat in the windmill.
Is it possible to have a dust explosion in a hotel air condition ducting system?
it is but i think its against health laws
Why is there a greater risk of explosion with dust in the air rather than dust on ground?
There is a greater risk of explosion with dust in the air rather than dust on ground. This due to the fact that dust combusts quickly and air supports combustion while the ground does not.
Why a spark can cause coal dust in a mine to explode and yet not cause an explosion with charcoal in a barbecue grill?
It is a question of the fuel oxygen ratio. Coal dust has a very high mix rate and as such will burn so quickly it is a form of explosion. A briquet has a very low surface area and is not as volatile. Note that any dust will explode. Flour has always been dangerous and grain silos are built to contain massive explosions.
What will happen if a person blows air through the tube at A to disperse the flour above the burning flame?
All of the surface area of all the particles of flour will be exposed to ignition at the same time, and a flash fire or explosion will take place. Flour in a solid clump is barely combustible, but as a dust mixed in the air, VERY explosive.
Was the wheat crop crash in the depression because of the dust bowl?
no the wheat crop crash was in 1928, the dust bowl happend in 1934
What is the name of radioactive dust after nuclear explosion?
fallout
Is sugar flamamble?
Sugar dust particles will ignite and this will be called the primary explosion, the primary explosion will unsettle more dust and cause a secondary explosion and the second blast will be more powerful. This then can be at threat to other easily combustibles items in the vicinity.
Why does bottles of powdered metals reads explosion possible?
Many common powders made in industry are combustible; particularly metals or organic materials such as flour. Since powders have a very high surface area, they can combust with explosive force once ignited. Facilities such as flour mills can be vulnerable to such explosions without proper dust mitigation efforts. Some metals become especially dangerous in powdered form, notably titanium.
Why does the sky turn black after a nuclear explosion?
It might be because of dust in the atmosphere elevated by the explosion. Particles of dust absorb and scatter visible light very well. And the sky turn to black because there is on light coming through dust clouds.
