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.

Abstract: The present invention relates to a method for producing pumpable coal-water suspensions by grinding pre-comminuted coal with water in a packed column in a ratio corresponding to the composition of the suspension ready for use. The addition of water or coal is controlled by measuring the density of the suspension leaving the mill, and the grain size of the coal particles is controlled by measuring the viscosity of the suspension. The density and viscosity of the coal-water suspension are simultaneously mutually adjusted. The addition of additives to the water is regulated according to the amount of coal added to the mill. The coal-water suspension can be fed to a coal gasification reactor without substantially changing the relative amounts of coal and water in said suspension.
