Measurement of the sub‐sieve particle size distribution of flour

Particle size distribution of samples of fine flour produced by centrifugal air‐classification, have been measured by the automatically recording Bachmann‐Sartorius sedimentation balance, and the results obtained compared with those from other methods. The performance of this apparatus was well within the limits recommended in a British Standard Specification. Cyclohexane and cyclohexanone were found to be suitable dispersion media.
