With a Kst value like that, it's explosive.
Do your risk analysis for the equipment to establish what the ignition hazards are. ■
Inertizing Possible?

Hello,
consider inertization as an option
you have to know if the gases can influence your product
The gaes to inertize are usually CO2 or N2
If this gases makes changes in your product you have to think about other explosion protection choices
this depends also on the size of your reactor or mixer
with the inertization you need to meassure de oxigen content; this is important to use the right quantity of inerting gas and not more
Check which is the limit of oxigen concentration in your case to avoid an ignition

Criterion for Inerting Solids
Following is the data for the powder we will use in our process. Powder from the gravity feeder feeds through a compounding extruder where it mixes with rubber. No flammable solvent/vapors are present.
Max Explosion Pressure : 6.94 Barg
Max rate of Pressure rise : 808 bar/s
Kst: 219
No information is available for LEL, MIE or resstivity. Particle size : fineness through 100 mesh. 99.9% minimum.
Is this powder explosion? I definitely do grounding for the gravity feeder. Do I need any inert gas for feeder bin?
Appreciate your advice ■
