2009-7-30 The standard inclined screen has an angle of inclination of 15 o. Lower angles of inclination increase the projected area of the screen aperture in the horizontal plane and the screen can handle a greater load. This is accounted for by capacity factor K6 K 6 1.0 0.01(. 15) (4-11) where . is the angle of inclination in degrees. The wet screen ...
