Abstract
A roller crushing machine for progressively crushing solid particulate material into finer size particulates is disclosed. It has a plurality of spaced-apart crushing stages arranged so that, a flow path of particulates travels consecutively from one crushing stage to the next, in between the outer peripheral surfaces of the rollers, which are adjustably displaceable from each other by a lateral distance not greater than a desired maximum particulate size from that crushing stage. When a flow of solid particulate material passes between cach of the pairs of rollers, the predetermined lateral distance encountered by the flow path can be controlled to be of a dimension which is sufficiently operably narrow to only apply a sufficient compression breakage force to just the topsize of the particulates at that size range of preselected solid particulate material, and a mono-layer flow of particles passing therethrough, to minimize energy consumption in that stage.
