A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, and medium filling rate of 90%.

The qualitative efficiency of non-conventional grinding has been estimated during the machining of steel H20N1252 by face grinder with CrA, 80-K-6-V segments. Steel H20N1252 is the material hard to grind, showing tendency to the formation of built-up edges on abrasive grains and the gumming up of the active surface of the grinding wheel.
