Fibre suspension impurity removal - through clearing channels mounted in stationary perforated drum under valve control

Designed for the removal of impurities from the fibre suspension to be used in paper mfr., the suspension is swirled through a perforated drum enabling the impurities to be spun out against the surface to build up in a layer, and to be passed through regularly-spaced apertures into clearing channels...

Zusammenfassung:	Designed for the removal of impurities from the fibre suspension to be used in paper mfr., the suspension is swirled through a perforated drum enabling the impurities to be spun out against the surface to build up in a layer, and to be passed through regularly-spaced apertures into clearing channels operating under valve control. This reduces the lengths of the impurity layer, by the aperture interval, to improve the removal of collected impurities and prevent the surface of the drum from becoming clogged.
