Apparatus for production of stable slurry of milled coal and a hydrocarbon oil

摘要

The apparatus comprises a milling machine including a heated rotatable drum connected to means for supplying coarsely crushed coal and preheated oil to the drum wherein the coal becomes finely ground and homogeneously mixed with the oil, and having a discharge duct rotatably connected to the drum and slidably connected to a stationary discharge tower in which the coal/oil slurry is separated from water evaporated from the coal during milling.
