ABSTRACT:
A combination of raw coal and water is introduced as a slurry into a vessel. Chemicals are introduced at a feed inlet. The mixture is reduced by interaction with a bed of agitated grinding balls. Air is introduced into the lower portion of the vessel and forced upwardly through the circuitous passages among and between the grinding balls. The rising air bubbles carry the more hydropholic product upwardly into a froth compartment of the vessel and through a discharge outlet of the vessel. Wash water is introduced into the upper portion of the vessel and descends through the froth and the ball passages carrying entrained and less hydrophobic particles into the grinding chamber. The non-floatable material flows downwardly from the grinding chamber to a refuse zone for discharge as refuse from the vessel.
