Abstract. This paper discussed the ultra-fine grinding and in-situ modification of Taixi super-low-ash anthracite in stirred mill. Particle size distribution of the products was determined by laser particle size analyzer. The surface morphology and dispersion of the powder were detected by scanning electron microscopy (SEM), and surface structure of the modified powder was measured by Fourier transformation infrared (FTIR). It was found that the optimum ultrafine grinding time is 70 min in the stirred mill, the suitable maleic anhydride (MAH) dosage was 1 wt% of the ground coal powder, MAH can play roles in grinding aid and modifier. On these conditions, both the grinding and dispersion effect are the best.
