为了克服湿微细粉易于结团形成“细粉群”、不易流化和干燥的缺点，在微细粉中加入惰性大颗粒物料，由于大颗粒的“搅动”作用，使细粉分散，可提高流化质量，从而提高微细粉的流化干燥热效率．在实验基础上进行了物料衡算和热量衡算，并进行连续干燥热效率的计算．该方法为微细粉的流化干燥提供一条新的途径．
In order to overcome the shortcoming that the wet fine powder is easy to form a “fine powder group” and is not easy to be fluidized and dried, an inert large particle material is added into the fine powder to disperse the fine powder due to the “agitation” effect of the large particles to improve the flow Quality, thereby increasing the fine powder fluidization drying thermal efficiency. On the basis of experiments, the material balance and heat balance were calculated and the thermal efficiency of continuous drying was calculated. The method provides a new way for the fluidized drying of fine powder.
