“…A major disadvantage of the previously used milling equipment is the fact that during the milling process, due to the pressure and impact of the grinding bodies, agglomerates and aggregates have been formed to a chamber wall and thus significantly reduce the efficiency of the milling process. The formation of aggregates and agglomerates [22] is an adverse effect in the processing of fine particulate materials, respectively nanopowders [1,6,7,13,[27][28][29]. As with other grinding equipment mentioned by authors [9,11,16,21,26,31,32], there is a grinding effect taking place by combining factors: pressure, impact, attrition, size distribution, electrical discharge, fluidization etc.…”
