Coal powder processing
Moist coal should be dried first, and then sent to the main grinding room for grinding. The fine powder after grinding is classified by the analyzer under the action of the air flow of the fan, and the qualified fine powder enters the collection stage through the air outlet pipeline.
Grinding of Coal to a Pulverized State
Existing Methods of Coal Grinding . In practice, special devices, called mills, are used for the grinding of coal. Ball pulverizer mills can grind and dry soft fuels with a high humidity content at the same time. They can grind coal to the pulverized state, but have the disadvantages of bulkiness and complexity, as well as a high rate of electricity consumption. Ball and roller mills are not ...

Influence of Organic Aerosol in Coal Mines on the Ignition ...
· Abstract It is shown that during mechanical action on coal, along with the emission of gaseous combustible compounds, highmolecular hydrocarbons are released, which, in turn, leads to the formation of an organic aerosol. The lower limit of ignition of a methaneair mixture with an organic aerosol is determined. The methane and aerosol concentrations varied within 0–50 g/m3 and 0– .
