Loesche developed the 4-roller coal grinding mill with four tried and tested modules for throughputs over 150 t/h. The develop-ment was first realised in 1970 for grinding mills in the cement industry. This number of rollers also enables operation with only one pair of rollers to increase control response availability and flexibility.
