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.

What are specialized Cables for explosion proof wiring?
Cables usually aren't the problem for explosion proof electrics and electronics. Switches, (motor/generator)brushes, breakers and relays are a (much) bigger issue. Followed by things using, or emitting electro-magnetic radiation. I assume, if you want to be thorough, one could use cables with a higher insulation/shielding rating for further protection in an explosion-prone environment.
Should I have an explosion proof fan in my garage?
It is imperative to use an explosion proof fan when working with flammable objects as the littlest spark or even heat build up in the fan could cause an explosion. While explosion proof fans are more expensive than their non-explosive counterparts, however, the safety they provide is worth every penny.
How are explosion proof refrigerators manufactured?
Explosion proof refrigerators are manufactured encased in steel. Their cabinet interiors are sparkproof with a non sparking magnetic door gasket with foam in place.
Is explosion proof and flameproof electrical equipment the same?
yes
Definition of explosion proof?
resistant to explosions resistant to explosions
Can you buy 190 proof grain alcohol in Maryland or Ohio?
You can buy 190 proof grain alcohol in Maryland. In West Virginia and Ohio, you can only buy 150 proof grain alcohol. I know in Maryland you buy either Everclear or Gemclear (generic version of everclear but same proof). The difference in price is about $5 per half gallon.
Are LED lights explosion proof?
LEDs are not automatically explosion-proof. It would depends on the design as a whole. what type of switch that's used, how well it's encased, amount of current running through it, etc.
What are the motor enclosures?
A motor enclosure is a structure containing an electric motor. There are many different types including the drip proof, totally enclosed, and the flame proof.
What are the special cables required for explosion proof wiring?
I thnk...it cn b ZHFR,FLR cables r suitble for explosion free wiring
What is pga alcohol?
Pure Grain Alcohol; usually containing a very high alcohol proof/percentage (i.e. 100 Proof, 50%)
Do water based paint spray areas require explosion proof fixtures?
No, they do not. No explosive fumes are produced.
