7-brain (1) for screens in mills, where the screening box consists essentially of a screening surface and a collecting floor covering the screened milling process, the single screening layer (1) in the screening box consists of a surface-type (2) made of flexible plastic material, with the surface facing the underside of the screen (3) of the cleaning body in the condition used in the screening cabinet fitted with knots (4) and/or brushes (5),and where the underside (6) of the sieve-bearer (1) pointing to the bottom of the sieve-beacon (7) has a tapered foot (7) for the production of a tilt and torque motion in the sieve-beams swinging in the plane-view-view, thereby characterized, that the seven-brain niger (1) is equipped with at least one electrical or magnetic signal device (8),the signals of which are detectable by a receiver outside or inside the visor (9) and the signals can be read and evaluated by means of a device (10) to monitor the individual screens located in the screenboxes (11) in the oscillating visor (1) and to control the Vision.
