The Conflo Refiner-A New Conical Refiner Concept for LC-Refining

Abstract

The stock preparation refining is considered the most important stage in paper making process. Not only it affects runability of paper machine but it determines quality of paper. And it influences furnish composition and energy consumption which directly influence production cost. The Conflo refiner have a shallow cone angle and short cone. These features ensure long stock retention time inside of refining zone and stable gap clearance. As a result, fibers get gentle, homogeneous treatment which cause a better tear-tensile combination, or a better tensile strength at the same freeness. The Conflo refiner can also keep lower idling power by virtue of increasing effective refining surface area with minimum increase in outer diameter of fillings.
