Classification wheel for centrifugal wind classifiers

摘要

The sifting wheel (1) is made from simple design cylindrical ring elements (2,3,4,5) connected together by a filler which is introduced into the gaps (10,11,12) between the ring elements and then left to solidify. The ring elements are finished and balanced prior to adding the filler. The filler can be adhesive or solder metal. The width of the gaps between the ring elements is 0.1 mm max. Narrow distance strips inserted in the gaps evenly spread out round the circumference centre the ring element and ensure even gap width.
