  • Patent number: 6508364
    Abstract: A sieving device and the operation of a sieving device are proposed. The sieving device has a supporting frame which can be made to vibrate and a vibration frame which is held so as to be able to vibrate freely in relation to said supporting frame. A simple, compact design which provides good sieving and conveying performance is achieved in that the vibration frame is spring-elastically coupled to the supporting frame by helical springs, with the main spring axes of the spring elements extending in the direction of vibration of the tension waves. Furthermore, guiding elements for movable bearing arrangement of the vibration frame on the supporting frame are provided. The sieving device is operated in particular at a vibration frequency of at least 850 vibrations per minute at an average speed of approx. 11 m/s and at an average acceleration of the vibration frame relative to the supporting frame of approx. 2.2 m/s2.
