VIBRATING SCREEN FOR SCREENING AGGREGATES AND/OR SOILS
A vibrating screen for screening aggregates and/or soils. The screen includes a body (1), a chute shaped stationary screening deck (6), which is fixed to the body (1) by its opposite ends. The stationary screening deck includes stationary screen-ing flat bars (8), which form first screening slots (8a) between them, and which have a curved shape corresponding to the shape of the stationary screening deck (6). The screen further includes a chute shaped vibrating screening deck (7), which is supported to the body by eccentric shafts (2). The vibrating screening deck (7) is arranged to be vibrated by machine power by rotating the eccentric shafts (2) synchronously with each other, thereby each point of the screening deck (6, 7) is in revolving motion continuously in the same rotating direction along a circular path when the eccentric shafts (2) rotating. The vibrating screening deck (7) comprises vibrating flat bars (9), which form second screening slots (7a) between them and whose curved shape corresponds to the chute shape of the vibrating screening deck. The vibrating flat bars (9) are located in the first screening slots (8a), and the screening decks (6,7) are positioned at such a height level in relative to each other that during one cycle the vibrating flat bars (9) rise partly above a screening surface formed by upper edges of the stationary screening flat bars (8) at different sections of the stationary screening deck (6) one after another and at different times.
