摘要： A method and a system distribute fluidizable materials from a reservoir of materials to one or more material receiving units. The distribution system has at least two hydraulic levels between the reservoir and the material receiving units. The system further includes a fluidizing element with good dynamic response properties. The system can be used for distribution of alumina and/or fluoride to feeding equipment in electrolysis cells with a reduced consumption of fluidizing gas.
