With ultralow ash Taixi anthracite chosen as object of research, the influence of milling time on crushing effect of ultralow ash Taixi anthracite in stirred mill is analyzed. Laser particle-size analyzer is adopted to analyze particle size distribution of products, based on which the crushing process of ultralow ash Taixi anthracite in stirred mill is analyzed. The result shows that ultralow ash Taixi anthracite undergoes the process of ?crushing-reunion-break apart? in stirred mill and optimum milling time is 70 min; at the same time, selective crushing occurs in stirred mill and crushing model accords with surface crushing model, so the theory that ultralow ash Taixi anthracite accords with selectivity-surface crushing model is put forward.
