Abstract: A vibratory screening device for dressing, sizing, desliming, and dewatering feed streams of fine particulate material is comprised of a vibratory sieve bend screen and a vibratory planar screen deck. The sieve bend screen is positioned at the feed end of the planar screen deck and is arranged so that linear vibratory motion acting on the sieve bend screen is substantially tangential to the arcuate midsection of the sieve bend. Advantageously, the two units can be mounted on a single frame so that only a single vibratory drive is required for imparting linear vibratory motion to both the sieve bend and the planar screen deck. The linear vibratory motion is preferably at an angle of about 40.degree. to the main planar deck and imparts a counter-current force to the fine particulate material flowing across the mid-section of the sieve bend.
