Abstract

A device for fractionating pulp suspensions has a series of vertical filter sheets attached to a horizontal shaft. Suspension is sprayed against the sheets to effect a separation of coarse and fine solids. Cleansing liquid is also sprayed against the sheets to keep the filter holes open and the fabric sheets are movable with respect to the sprays.
