FIELD: milling technique. ^ SUBSTANCE: combination of spherical milling bodies charged into drum mill comprises milling bodies with depressions on their surfaces, made in the form of closed annular grooves, and spherical milling bodies free of depressions, said milling bodies being used in the ratio of 1/10-9/10. Radiuses of milling bodies free of depressions should be equal to 1-0.5 the radius of cross-section of depressions provided on milling bodies equipped with depressions. Said ratios refer to all the sizes of milling bodies charged into mill. ^ EFFECT: intensified milling of mineral crude material, increased efficiency of mills and reduced consumption of power. ^ 2 cl, 2 dwg |
