Abstract
Method and apparatus for treating a fluid mass or stock, particularly couch stock or the like in paper making. Stock material is fed to a vessel having a mixing arrangement comprising rotatably arranged processing means. At least two processing means are caused to rotate mutually adjacent in opposite directions and substantially horizontally. The stock at the upper surface of the means is conveyed towards a wall potion of the vessel, whereby spirals arranged in an inclined manner at a core of the processing means bring the stock into channels defined by the core, by the spirals, and by the wall portion of the vessel, and further towards a constriction formed by the spiral elements running in an intermeshed manner, while a part of the stock is forced in a direction away from a discharge of the vessel.
