20 years of the Horomill – a review*)

mance of the Horomill will be illustrated by some selected industrial results in Table 1 The Horomill leads to large energy savings more important with harder to grind ma- terials such as slag cements or pure slags In comparison to the classical ball mill the energy savings are between 30 to 50%

in the discontinuous ball mill Abstract During ceramic tile production (wall floor and porcelain stoneware) wet milling process for the preparation of ceramic slurries is widely used The currently preferred wet grinding machines are discontinuous and/or continuous ball mills where grind-ing occurs when a particle is crushed

Wet vs Dry Grinding

30 01 2012There has been a well established "truth" that wet grinding is more efficient than dry grind- ing This should apply to ball mill grinding as well as autogenous grinding It has been earlier shown that the effect of dry ball mill grinding increases considerably when the fines are efficiently removed from the mill In this work autogenous grinding in small continuos scale has been
