Abstract
A floatation tower for paper recovery has a set of cells one above the other, holding the fibrous paper paste, and into which water and compressed air are injected so that the impurities mix. with the bubbles to form a foam which can be removed separately. Water is admitted as a thin layer at the same time as the air to mix. with the liquid paste as it is circulated in a thin layer in a mixing chamber, passing it through and along the flow, controlling the thickness of the layer. Air is then admitted to skin off the foam and drive it into a collector vessel below, for recycling. By a similar process for each cell, ink, kaolin and fibres can be removed separately. The mixing chamber is conical, with a tangential lop entry.
