Deforming and grinding device for rocks and rock mixtures

摘要

The deforming and grinding device has a roll mechanism comprising two contra-rotating rolls (1, 2). The cross-sections of the rolls perpendicular to their longitudinal axes are in the form of freely selective polygons, forming surfaces (7, 7') and edges (6) on the roll surface to carry out the grinding function. By the synchronous running of the two rolls, selective grain formation of the rock mixture (5) is possible.
