Research on fragmentation quality percentage of coal in hot air dense medium fluidized bed

Abstract

This paper studies the percentage of pulverized coal in the hot air dense medium fluidized bed, and investigates the influence of coal surface moisture, drying temperature, drying time, air volume and other factors on the percentage of crushing, and establishes a mathematical correlation formula for the percentage of crushing; it shows that with the increase of drying temperature, the percentage of crushing increases; with the increase of air volume, the percentage of crushing increases; the percentage of crushing increases with the increase of drying time and increases with the increase of surface moisture of coal.
