FIELD: coal processing industry.
SUBSTANCE: invention relates to processes of obtaining liquid fuel, in particular to preparation of water-coal fuel intended for hydro-transportation and direct combustion. Process is accomplished by grinding starting material and homogenizing it in dispersion medium consisting of mixture of fine and coarse coal fractions , the former being preliminarily ground with dispersion medium in dispersers operated at power intensity 0.2-1.5 kW/L.
EFFECT: enabled preparation of low-viscosity high-concentration suspension with high content of solid phase.
