  • Why is diamond harder than coal ifUCSB Science Line

    These structural differences result in very different material properties, such as hardness. According to the Mohs Hardness Scale, numbered 1 (softest) to 10 (hardest), coal is a 1 or 2 whereas diamond is a 10! The carbon atoms in coal are arranged in 2D sheets, where each carbon atom is bonded to 3 other carbons to form hexagonal rings.

  • EnergiesFree Full-TextModeling on the Effect of Coal

    Ball mills, which grind coal to a target size prior to boiler combustion, are important auxiliary equipment in thermal power plants. Their coal grinding efficiency is closely related to the economy of the power plant, as discussed by Masiuk, et al. [].The control requirement for a pulverizing system is to guarantee that the coal load in the ball mill is close to the optimum level.
