Uses :The tangential inlet accelerates the stock to downward centrifugal motion.Impurities with high specific gravity are forced to the outer wall of cone and downward to collect in a trap.From hole they are isolated and removes through a chamber with intermittent or continuous discharge.Thus clean stock rises through the middle of vortex towards the outlet. Main features: l Easy visual inspection of vortex through illuminated sight glass; l Easy and simple to handle and maintain; l Working consistence is from 2% to 5%; l High consistence,save energy and chemical,no fiber loss and clogging free operation; l Long lifetime design with ceramics cone.
