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.

Provided is a method that, when pulp fibers are recovered from used absorbent articles that have been put into collection bags, makes it possible to safely and sanitarily crush the used absorbent articles while suppressing costs. A method for recovering pulp fibers from used absorbent articles, the method comprising: a crushing step (S12) in which collection bags (A) in which used absorbent articles have been sealed are put into a container (65), the collection bags in the container are transferred to a crushing device (12) that communicates with the container, and, bag by bag, the crushing device crushes the used absorbent articles in the collections bags in a deactivating aqueous solution; and a separation step (S13) in which the pulp fibers, a highly water-absorbent polymer, and the deactivating aqueous solution are separated from the crushed product and deactivating aqueous solution obtained in the crushing step.

An agricultural implement comprises a container mounted on a frame arranged for movement across an agricultural field, which container is suited for storing a granular product to be deposited across the field. The agricultural implement additionally including a metering system arranged for metering the granular product in movement from a product exit of the container to a product discharge, typically in operative communication with a pneumatic conveying system, for eventual delivery to the agricultural field. The agricultural implement features a crushing system arranged for reducing a size of the granular product that is disposed in series with the metering system so as to be located between the product exit and the product discharge, such that metered quantities of the crushed granular product can be deposited into the ground as the agricultural implement is displaced in the forward working direction across the field.
