Overview

The Powder Feeding and Slurry Handling System is a floor standing system designed to produce, homogenise and transfer powder-ethanol slurries. Plastic mixing pots and ceramic crucibles are loaded to the system using a four quadrant indexing rack. This can done before or during a process. Powders are fed to the mixing pots before ethanol is added to create a slurry. The mixing pot is agitated in a dual asymmetric centrifuge (DAC) to homogenise the contents. After sufficient mixing the slurry is pipetted from the mixing pot into a crucible. The crucible is then heated to evaporate the ethanol leaving a dry, even powder distribution.
