ABSTRACT:
A screening apparatus has a screen grid including plurality of exchangeable elements, each having a screen surface with sieve openings. The screen elements are placed in direct contact with each other to form a continuous screen, sifting surface and are removably connected through separators on intermediate cross-pieces. The separators are connected to the bottoms of the screen elements and extend at such a distance beyond the underside of screen surface so as to form an inwardly facing open passage space for sifted material below the screen, sifting surface in the area of connection of the screen elements to the separators such that the active sifting surface extends to the area of the supported marginal zones.
