  • Pulverizer - Wikipedia

    The pulverized material is carried out of the mill by the flow of air moving through it. The size of the pulverized particles released from the grinding section of the mill is determined by a classifier separator. If the coal is fine enough to be picked up by the air, it is carried through the classifier.

  • Coal ball - Wikipedia

    Thin sectioning was an early procedure used to analyse fossilised material contained in coal balls. The process required cutting a coal ball with a diamond saw, then flattening and polishing the thin section with an abrasive. It would be glued to a slide and placed under a petrographic microscope for examination. Although the process could be done with a machine, the large
