Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

Electrical safety is even more important in coal mines where sparks can ignite gases. In the previous topic, we learned that combustible gases such as methane occur in significant quantities and earlier in the this topic we learned that coal dust is combustible and potentially explosive. Sparks in coal mines must be prevented.
COAL HANDLING SAFETY Risks of unwanted combustion – potentially causing injury, damage and downtime – occur everywhere that coal is handled, processed or stored. Safe coal handling practices are designed to ensure that the fuel remains intact throughout its journey from the mine until the point at which it is ignited in the boiler.
A pulverizer hammer mill is a mechanical grinding device that is used for parting distinct types of materials. Coal and mining industry uses this device to pulverize coal for combustion in steam-generating furnaces for fossil fuel power plants.
