抄録

A new production process for Coal-Water-Mixture (CWM) has been suc-cessfully developed. It is characterized by high productivity per mill volume, and controllability of particle size distribution using a stirred ball mill and a roll mill. From the operation of a 300kg/hr plant, the following characteristics have been confirmed:<BR>(1) The particle size distribution can be controlled by mixing different-sized balls in the stir-red ball mill.<BR>(2) The power requirement of the stirred ball mill is 40-60kWhr/t·coal. This is com-parable to a conventional tube mill.<BR>(3) The coarsest particles can be effectively eliminated by using the roll mill, instead of using a screen.<BR>(4) The measurements of the rheograms and settling tests done over a six week period show-ed that the CWM produced by this process had good slurriability and stability.<BR>In addition, We determined that the Davcra Cell Coal Cleaning process can be applied to CWM preparation. Further investigation showed that a Davcra Cell characterized by formation of fine air bubbles proved to be efficient in the cleaning of fine coal particles.
