Abstract

La invencion se relaciona con una maquina de flotacion, particularmente un rotor de una maquina de flotacion, que se utiliza para dispersar aire, suministrado a traves del eje del rotor, hacia la lechada circundante, y rotor en donde se forman conductos de aire alternantes y ranuras de lechada, de manera que los extremos tanto de los conductos de aire como de las ranuras de lechada, proyectandose hacia fuera desde el rotor, forman la superficie exterior del rotor. De acuerdo con la invencion, los conductos de aire (3, 15) estan arreglados en el rotor a distancias esencialmente iguales, comenzando radialmente desde la superficie exterior del rotor, de manera que los conductos de aire (3, 15) forman en la parte central del rotor un espacio (6, 17) para la lechada, espacio en el que la lechada que circunda el rotor va a ser hecha fluir a lo largo de las ranuras (5, 16) de lechada proveidas entre los conductos de aire (3, 15).
