Sažetak
Obtaining and controlling desirable suspension behavior in terms of rheology is important issue in many engineering problems. This research monitors rheological behavior of dolomite suspensions produced by wet comminution in planetary ball mill. Dolomite has a number of uses, in agriculture, steelmaking, glass making, ceramic industry, pharmaceutical industry etc. therefore it is very interesting for investigation. Rheological behavior of attained suspensions was characterized as strongly pseudoplastic whereas the degree of pseudoplasticity was connected to particle size distribution. Rheological properties of the product become equal after the effective comminution time regardless of primary particle properties before comminution. Therefore the comminution in a highly energetic mill such as planetary ball mill, within short time interval will lead to development of systems with the same granulometric and consequently the same rheological properties regardless of the primary system properties before the comminution.
