A vibratory screener includes a screen carrier frame having inner and outer circumferences, a horizontal screen for separation of solid particles within and vertically supported by the frame, one or more vibration motors on the outer circumference of the screen carrier frame and configured to generate vibration perpendicular to the screen, and at least two internal annular disks each having an inner rim and an outer rim. Each internal annular disk is attached to the inner circumference of the frame by its outer rim, the internal annular disks are spaced apart from each other in parallel planes, and an inner sleeve is arranged within the frame. The inner sleeve is attached the inner rims of two of the internal annular disks, where the upper internal annular disk and the inner sleeve provide an unbroken surface and where the lower internal annular disk has openings towards the outside environment.
