title: An automated sedimentation balance.
abstract: A method of size grading powders using an automated sedimentation balance is described. The results are recorded as percentages of the total powder present in 1 or 5 mum (intervals) of particle size, after they have been multiplied by a simple correction factor. Analyses of calcium carbonate powder using this balance and the Gallenkamp balance have been compared.
