The frame has a bottom surface and a substantially planar top surface. The top surface extends from the screen portion to the discharge portion. An opening located in the screen portion of the frame extends through the frame from the top surface to the bottom surface. A spout formed in the discharge portion has a shape of a hollow cylinder and extends through the frame from the top surface to the bottom surface. A system has a separator with an inlet into which material to be separated enters. A unitary screen frame has a screen portion and a discharge spout with a planar top surface extending from the screen portion to the discharge spout. A first portion of the material entering the inlet flows from the planar top surface to the discharge spout. | 11-05-2015 |
