In order to convert these raw materials into clinker and cement, it is necessary to produce a raw mix with a top size of about 0.2 mm. The reduction ratio required for most raw materials is consequently 1000-2000:0.2 or 5000-10,000. It is obvious that such a degree of comminution cannot be achieved through a single machine or a one-stage operation.
