ABSTRACT:
The purpose of the invention is a process and a machine for the fine grinding of materials such as cement clinker. To improve the energy efficiency of the operation, by performing a systematic grinding, without resorting to excessively high pressures or excessively substantial recycling rates, there is used a mill composed of a rotating path and a roller capable of rolling on the path, exerting on the material by means of the roller an average pressure between 10 and 40 MPa and, on each turn of the path, the material is moved transversely on the latter over a distance which is a fraction of the width of the path.
