The need for Loesche mills for grinding cement raw material skyrockets at the start of the 1960s. The reason for this trend is the technological development in the cement manufacturing process which moves away from the energy-intensive wet pro- cedure to the semi-dry process and ultimately to the dry pro- cess with precalcination.
