SANDWICH SCREENS

SANDWICH SCREENS™

The anti-blinding Derrick Sandwich™ screen consists of two fine mesh screens supported by a coarser backing wire screen. Interference in the free openings is created by cross wires of the second screen. This layered effect prevents particles from lodging in the openings of the top sizing surface and provides longer screen panel life. The cut point is made by the combination of cross wires from both fine screen surfaces.
