摘要

Vibration sifter for loose materials e.g. crushed stone has continuous sifter material carried on support rollers between side panels, with drive and vibration mechanism. The machine has a main frame (1) with suspended side panels (3), sifter material support rollers (5) between the rollers, and a continuous sifter material (4) between the panels. The sifter material has an upper bridge section (4A), which is supported on the rollers, so that it extends continuously in longitudinal sifter direction from a charging station to a discharge station. The sifter material is moved by a drive unit (17, 17A, 18, 14, 14A). An eccentric rotary vibration mechanism (6) is coupled to the side panels to vibrate the rollers and bridge section of the sifter material.
