Abstract
Liquid is supplied within a substantially vertical mixing chamber in a substantially tangential manner from a chamber top section, such that the liquid is deflected for rotatory motion against a chamber wall while advancing, in response to a pressure difference, downwards in the direction of a chamber longitudinal axis. Pulverous material is supplied by compressed air into the chamber () from the top section and into an air core (A) established by the liquid in rotatory motion, such that the pulverous material containing little air, and by being heavier than the air contained in the pulverous material and/or used for carrying the same, is driven in response to a centrifugal force into the liquid in rotatory motion, and the air separates towards the eddy center, and that the liquid containing pulverous material and the air supplied into the chamber, are discharged through an open bottom section of the chamber ().
