how to increase fineness of coal mill in Vietnam Холбогдох мэдээлэл

• Fineness - an overview | ScienceDirect Topics

  The fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system deteriorates.. fineness of coal required in thermal power plantThe coal is pulverised to fineness such that 70-80% passes through a 200 Mesh sieve. Normally low speed ball mills or medium speed vertical spindle mills are employed in thermal power plant for this purpose. The milling system is an important
