Dust explosionIn the coal mining industry, a methane explosion can initiate a coal dust explosion, which can then engulf an entire mine pit. As a precaution, incombustible stone dust may be spread along mine roadways, or stored in trays hanging from the roof, to dilute the coal dust stirred up by a shockwave to the point where it cannot burn. Mines may also be sprayed with water to inhibit ignition. Some ...

firefiting system in coal millIf the coal mill temp goes high, it can ignite the coal and result in explosion inside the mill and components. Thats why the CO2 is injected into the mill to create a inert condition, means to reduce the Oxygen content inside the mill to avoid any firing/explosion. If the CO2 system is not working, we can fill 5 tons of limestone dust/raw meal dust into the fine coal bin. This will act as a ...
