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 w...

A process for producing a coal-water suspension useful as a feed for coal gasification which comprises mixing coal and water in a packed mill in a ratio corresponding to the ratio of the desired suspension, passing said coal-water suspension from said packed mill to another vessel, simultaneously mutually adjusting the density and viscosity of the resultant coal-water suspension by determining the density of said suspension after leaving said mill, regulating the amount of water to said mill at constant coal addition in response to a change in density of...
