ABSTRACT:
A coal-water suspension containing 50 to 75 percent by weight coal, based on the weight of the suspension, the bulk of the coal having a particle size of 50 to 500 .mu.m, the proportion of the particles having a diameter greater than 0.5 mm in the coal being less than 15 percent by weight and the particle size distribution curve of the coal in the Rosin-Rammler particle size distribution grid according to DIN 4190 having a slope of .gtoreq.1; a process for the production of such water-coal suspension which is suitable for use in coal gasification under elevated pressure by mixing lump coal with water directly, the water being added in a concentration just sufficient to form a water-coal dust suspension suitable for the gasification reaction and grinding the resultant suspension in a disc attrition mill, a toothed disc attrition mill or a toothed colloid mill.
