Abstract
Abstract A screen assembly for a vibratory screening machine including a frame, and a screen cloth on the frame having wires with a diameter D of between about 1.6×10 3 micrometers and 17.8 micrometers with a peak to valley roughness R in micrometers which is between about R=0.333D and R=0.05D. A screen cloth for mounting on the frame having a range of dimensions as set forth above. A method of making a screen for a vibratory screening machine including the steps of providing a screen cloth having a wire of a diameter D of between about 1.6×10 3 micrometers and 17.8 micrometers and roughing the surface of the wires to a peak to valley roughness which is between about R=0.333D and R=0.05D.
