  • Effect of drying conditions on moisture re-adsorption and

    In raw coal, the moisture of fine particles is higher than that of coarse particles. However, fine particles easily lose water, so the moisture content of fine particles is always lower than that of coarse particles by approximately 0.5–1.1% after drying begins. During drying, heat carried by hot air is transferred from the particle surface
