Grading suspensions of mineral particles of - different weight

摘要

Grading suspensions of mineral particles of different weight Device comprises a cylindrical centrifugal chamber with a discharge aperture for heavy substances at the bottom, and an overflow chamber with an aperture for light material. The chamber bottom is formed by a displacement body which projects into the chamber and decreases in height with increasing distance from the cylinder axis. An annular chamber tapering downwards is thus formed at the bottom end of the chamber. At the lowest point of the ring are apertus for the suspension which is enriched in heavy material. The device is connected with a vibrator producing vibrations towards the cylinder axis. The device and vibrator are jointly fixed on a firm base.
