This article briefly describes the coal slurry preparation process.Combined with the actual production situation of preparation of coal water slurry pressurized gasification coal slurry of a company,the preparation of high-concentration coal-water slurry is analyzed based on several main factors that affect the concentration of coal-water slurry.It is necessary to control the gradation of steel rods in the coal mill,adjust the height of the coal slurry discharge trough pump outlet pipeline,the washing water of the drum screen of the coal mill,the amount of coal slurry additives,the application of ultra-fine grinding systems and other key control points.Based on the comparison of actual measurement data in production and years of operating experience,put forward corresponding improvement measures to provide some reference for the industry.
