<p>The subject of the invention is a method for the fine pulverising of minerals, consisting in subjecting a layer of the material to be pulverised to a compression between two rolls (10, 12) with parallel axes, rotating in opposite directions and pushed elastically towards each other, and a pulveriser for carrying out this method. In order to prevent the formation of agglomerates, the pulverised material is kept under pressure in the space (22) defined by the rolls (10, 12) immediately below the imaginary plane (X-X) containing the axes of the rolls by closing the said space by a member (14) forming a barrier. <IMAGE></p> |
