ABSTRACT:
The invention concerns a separator, wherein the mixture, after passing through the inlet channels of the container body (1), penetrates into the admission chamber (30) of the rotor (2), where blades (35) arranged in star formation and perpendicular to the axis of rotation produce a centrifugal propulsion and, further, compact the components with greater density, thus facilitating extraction thereof. The thus modified mixture passes into the separating chamber (31), where blades (36) arranged in star formation and parallel to the axis of rotation, through their centrifugal force, push the components with greater density outwards; the latter having penetrated into the collecting cells (41) of the grid (34) which is coated on the outside of the separating chamber, through holes (42) exit from the rotor upon reaching the accumulation chamber (13). The fluid medium which, countered by a suitable pressure, cannot penetrate into the accumulation chamber, exit through evacuation channels. An electromechanical control system (3) adjusts the functioning of the method.
