Abstract

A centrifugal concentrator in which there is a common shaft for the drive motor and concentrator bowl. The cost of bearing assemblies is thereby minimized. The bowl is driven and suspended from above to keep the motor out of the slurry area and maximize the simplicity of the design. A fluidizing fluid is delivered through the common shaft.
