Abstract (en)

[origin: EP0489633A1] Process for milling brittle material making it possible to obtain a very fine product. The raw material (1) feeds a roller miller (2) of which the product, which contains agglomerates, is sent to a disagglomerator-separator (3). The fine particles are evacuated (4) and the large particles are recycled (6). By way of a characteristic, the rate of disagglomeration is limited in the disagglomerator. Application to cement clinker and to various inorganic substances. <IMAGE>
