Since the performance of pulverizing system directly affects the pulverizing economy and combustion efficiency,the characteristics of pulverizing system under different lignite blending ratio are tested and studied in this paper.The results show that when MPS-HP-Ⅱ medium-speed coal mill works under the same separator speed and hydraulic loading force,with the increase of lig-nite blending ratio,the pulverized coal is tapering off;to ensure drying power output,with the increase of lignite blending ratio,the ratio of air to coal increases gradually,and the vibration of the mill increases gradually,thus the uniformity index of pulverized coal decreas-es gradually.At various blending ratios,the uniformity index increases first and then decreases with the increase of separator speed,and the uniformity index of pulverized coal increases gradually with the increase of hydraulic loading force.
