A particulate sizer includes an infeed for receiving a plurality of particulates, a first roller, and a second roller. The first and second rollers break down the plurality of particulates as the plurality of particulates passes through a gap between the first and second rollers. The width of the gap varies along a length of the first and second rollers. Accordingly, the first and second rollers compress some particulates to a first size and compress other particulates to a second smaller size. In addition, each of the first and second rollers has a textured outer surface for carrying the plurality of particulates through the gap.
