| Abstract: | This paper deals with the dry method preparation of the coal pulverized powder, and through a lot of experiments, discusses the main factors affecting the coal powder size. As a result, the desirable conditions of the grinding efficiency are determined, and the linear relation between coal powder size after grinding and ball/coal, grinding time, coal powder size before grinding is drawn as well, on the basis of statistics and programming. It will serve preparation of pulverized powders and size broadcasting in theory. |
