Abstract

A filter for ejecting fibers from a granular flow which includes a generally four-sided housing 1 having an input opening 2 at the top thereof into which the meterial to be filtered enters and an output opening 3 through which filtered powder emerges. The material entering the opening 2 passes through a first grate 4 supposrted within the housing at an angle to the flow. The grate 4 is comprised of a series of spaced apart parallel rods, the spacing being selected to trap fibers or other larger debris in the powder to be filtered and direct them through an opening 5 on one side of the housing. A second grate 6, similar in construction to grate 4, is disposed downstream of grate 4 at an angle to the flow of material to direct fiber out of an opening on another side of the housing. The powder which passes through both grates moves down the output chute 9 to a clean powder collecting zone 10.
