Cut off oxygen supply
Inert gas displaces air and lowers oxygen concentration far below sulfur dust’s limiting oxygen concentration, removing the essential combustion condition.
Terminate combustion chain reaction
It fills gaps between floating sulfur dust particles, isolates dust from oxygen, stops flame spread and restrains deflagration expansion.
Eliminate thermal ignition risks
Circulating inert gas takes away friction heat generated during grinding, lowers internal temperature and avoids high-temperature ignition points.
Prevent sulfur self-heating & spontaneous combustion
Isolate air to slow down sulfur oxidation exothermic reaction, avoid heat accumulation inside equipment.
Block external air infiltration
Maintain slight positive pressure inside the fully sealed system to stop high-oxygen outside air from entering, keep stable safe atmosphere.
Weaken explosion hazard
Even if tiny ignition occurs, low-oxygen inert environment can greatly reduce explosion pressure and destructive power.
