1. A vibratory screener (1), comprising:
a screen carrier frame (10) having an inner circumference (11) and an outer circumference (12),
a screen (20) for separation of solid particles extending horizontally within the screen carrier frame (10) and being vertically supported by the screen carrier frame (10),
one or more vibration motors (30) mounted on the outer circumference (12) of the screen carrier frame (10) and configured to generate a component of vibration in a direction (z) perpendicular to the screen (20),
at least two internal annular disks (14.1, 14.2, 14.3) each having an inner rim (15.1, 15.2, 15.3) and an outer rim (16.1, 16.2, 16.3), wherein each of said at least two internal annular disks (14.1, 14.2, 14.3) is attached to the inner circumference (11) of the screen carrier frame (10) by its outer rim (16.1, 16.2, 16.3), and wherein said at least two internal annular disks (14.1, 14.2, 14.3) are spaced apart from each other in parallel planes, and
an inner sleeve (17) arranged within the screen carrier frame (10) and connected to the inner rims (15.2, 15.3) of two (14.2, 14.3) of said at least two internal annular disks, wherein the upper internal annular disk (14.2) of said two internal annular disks and the inner sleeve (17) provide an unbroken surface whereas the lower internal annular disk (14.3) of said two internal annular disks is provided with openings (18) towards the outside environment.
