| 摘要 |
<p>This arrangement comprises a milling means enabling a plurality of cycles to be carried out in which the material is crushed slowly either by means of at least two communicating slow-compression crushers or by means of a slow-compression crusher (6) equipped with a system (9) for recycling the material from the outlet to the inlet of this crusher, whilst the pre-milled material is sent into a crusher containing balls (11), resulting in the final desired product which can subsequently be treated in a separator (13). The method and the arrangement of this invention permit, in particular, the milling of cement clinker. <IMAGE></p> |
