Abstract
A method and apparatus for enhancing knot transport in a knot drainer has a provision for decreasing tangential velocity of the feed slurry in the inlet chamber, a hydrodynamic force reduction provision in the screening chamber, and a provision for increasing the ratio of circumferential friction forces to axial friction forces in a housing extension above the screening chamber. This drastically reduces frequency of knot transport interruptions which would otherwise occur in the knot drainer, thereby improving knot drainer performance efficiency.
