ABSTRACT:
A multi-stage apparatus and process for separating wood chips of a desired size range for pulp production, from an intermixture of materials e.g. from a log chipper. A disc screen screens out the chips and other materials having a size larger than the designated size range. The chips are deposited on an air separating screen through which a vacuum is drawn to draw out the smaller size materials, e.g. sawdust, and to deposit the desired pulp chips for collection and conveyence to the paper processing station.
