This invention relates to a method of and comminuting aggregate (10) or any coarse material or mineral or a product from a material or a mineral, which needs to be reduced in size and to a comminuting machine (10) for aggregate or any material. The method of comminuting aggregate (10) includes the feeding of material in the form of aggregate into an at least partially enclosed space in a feed direction (F) and simultaneously creating in the space, airflow in first and second flow directions (D1, D2), and in a pattern agitating the material to inter-collide in at least, but not subjected to, one collision zone (40) in the space and, by such collision, causing the material to be fractured and thus comminuted. In a preferred method, the first an second flow dircetions (D1, D2) are: (i) substantially aligned and directed towards one another across the feed direction (F); and (ii) substantially co-axial with respect to one another. The invention extends to a machine (10) for performing such method. |
