a Loesche mill, with a grinding track diameter of only metres, was used as long ago as 1935. However, the breakthrough in grinding this type of material on the vertical roller mill did not take place until the beginning of the 1990's. 1935 The first Loesche mill for grinding cement clinker, an LM 11, was commissioned in Joao Pessao, Brazil.

Abstract. The determination of mean residence time is a powerful method for studying the holdup in a cement mill, and hence whether the mill is operating in the required steel to clinker ratio. To determine the mean residence time accurately it is necessary to correct for the recycle of tracer, and a method of correction is given.
