ATOX coal mill - FLSmidth

The ATOX coal mill has a water injection system to compensate for low water content in the raw coal, which allows increasing the amount of hot gas instead of recirculating gas at a level that would invalidate the inert condition of the grinding system. For most types of coal, the grinding systemPulverizer Application for High Volatile High Moisture Coals,the pulverizer system design lies in the selection of air to coal ratios to handle the specific coal property. Figure 9 shows a typical ball tube mill arrangement including crusher dryers. Figure 10 illustrates changes in air coal ratio necessitated by different coal characteristics.firefiting system in coal mill - Page 1 of 1,Re: firefiting system in coal mill. If 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.
