Abstract:
1. A method for mixing pulverous material with liquid in a substantially vertical mixing chamber comprising the steps of: setting a liquid in rotatory motion within the substantially vertical mixing chamber, by supplying the liquid in a substantially tangential manner from a top section of the mixing chamber, such that the liquid is deflected into rotatory motion against a wall of the mixing chamber; advancing the liquid downwards in a downward longitudinal direction along a longitudinal axis of the mixing chamber, in response to a pressure difference in the downward longitudinal direction; and supplying the pulverous material and air contained in the pulverous material by use of compressed air into the mixing chamber from the top section of the mixing chamber into an air core established by the liquid in rotatory motion within the mixing chamber, wherein the pulverous material is driven in response to a centrifugal force into the liquid in rotatory motion within the mixing chamber forming a liquid containing pulverous material, and the air contained in the pulverous material and the air used for carrying the pulverous material is separated towards an eddy center defined by the air core, and wherein the liquid containing pulverous material, and the air contained in the pulverous material and the air used for carrying the pulverous material, are discharged through an at least mainly open bottom section of the mixing chamber.
