✦ Synopsis

An a eratus for feeding pulverixed coal, water end an additive in a wettype &I miIl to obtain a raw slurry, and screening the raw slurry to remove the large grains, mixing the treated slurry with water and a second additive in a line mixer to give a highly-concentrated coal aqueous slurry. 96lOl262

The apparatus corn rises means for ball milling of coal feeds with water to form an aqueous 8 wry for screening the aqueous slurry to separate large P grams, monitoring water content, the weight of coat feed, water flow and dispersant weight means for controlling the coal slurry viscosity et e predetcrmlncd level, and means for optimixmg the amount of dispersaut supply based on the feedback signal from the monitors.
