Yes, it is combustible.
Anything that can burn is a combustible substance.
Perhaps amazingly, the answer is "Yes". Of course, when ground finely enough, almost ANY material is combustible; that's why there are grain silo explosions every summer, when wheat dust or corn dust, suspended in the air, reaches a critical proportion with air and then it will explode with the slightest spark. Aluminum dust is commonly used in pyrotechnics.
Cobustible substances can catch on fire but non-combustible substances are inflammabe
There are some simple requirments for something to be a convenient fuel - it must be abundant, easily collected and transported, cheap and ideally have a high calorific value per unit volume. Actually the question asked is wrong. Combustible subs. = Combustible materials all combustible subs./combustible materials are fuel but all fuel are not combustible subs/combustible material because fuel can also be an incombustible material/incombustible subs.
Silver is a non-combustible solid (except as dust)
It is not combustible like some materials, but it can catch afire which is why many shops have separate shop vacs for titanium dust/chips.
If the dust comes from a flammable/combustible material - sure. But you'd still need a flame or a spark to set it off.
Combustible Dusts have a KST value of Greater Than Zero, and can cause a Week to Very Strong Explosion... (Powdered Milk, Sugar, Coal, Wood, Plastic, Food/organic, Aluminum, Zirconium). Non-Combustible Dust, have a KST Value of Zero, and Don't cause an Explosion: Non-Combustible Dusts: Aggregates, such as stone, silica(sand), Silicates, Sulfates, Nitrates, Carbonates, Phosphates, Portland cement, Sand, Limestone.
i think it is not a combustible substance because it doesn't produce heat. ******************************************* No, examples of combustible substances are wood, paper, petrol, flour dust, etc. Iron will never burst into flames, though it will melt into a liquid if heated enough.

It depends on where in the grain elevator the motor is located and if dust is allowed to build up on the surface of the motor restricting its heat dissipation. Grain dust is highly explosive if the air dust ratio is correct. If the motor is outside or adjacent to an area where there is no dust then an ordinary totally enclosed motor can be used. Grain elevators fall under the classification of Class 2, Division 1, Groups E, F and G. Group designations for Class 2 areas refer to the type of dust involved. Group E dusts contain combustible metal dusts like coal and some other combustible dusts. Group G dusts are the combustible dusts not found in groups E or F.
