GRINDING SOLID FUEL-OIL MIXTURES

摘要

A uniform dispersion of a friable solid fuel, e.g. coal, oil and water is prepared by grinding the solid fuel in a medium consisting essentially of a major proportion of oil and a minor proportion of water in the absence of added dispersant or emulsifier. Air is excluded during the grinding operation. The solid fuel is present in amount 15 to 55% by weight of the dispersion and is ground until the mean particle size of the solid fuel is reduced to a value in the range 1 to 15 micron. The water enhances the stability of the dispersion.
