Abstract：T he study of ultra-fine comminution is carried out by using vibration mill and coarse tungsten powder as original ma terial．T he orthogonal tests are finished by using L8（2⁷）in the experiment process．T he best of milling time‚milling medium‚ ratio of ball to sample are confirmed by the variance analysis of orthogonal tests‚and the influence degree of each factor which is affecting to the milling process is confirmed．
