Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings. On the basis of the existing coal pulverization system, the pulverization system is partially modified by adopting high-efficiency dynamic separation technology and multiple classification and grinding technology. Such as figure 1 As shown in , the pulverizer storage type superfine pulverized coal preparation system includes raw coal bunker 1, coal feeder 3, drying pipe 4 with cold air door 19, coal pulverizer 5, dynamic pulverized coal separation device 6, coal For the powder bin 20, as an optimized solution, the dynamic pulverized coal sorting device 6 adopts various pulverized coal sorting technologies to improve the pulverized coal sorting efficiency. The raw coal 2 is transported from the raw coal bunker 1 through the coal feeder 3 and the drying pipe 4 into the coal mill 5, and the pulverized coal pulverized by the coal pulverizer is sorted by the dynamic pulveriz...
