摘要：
When a container partly filled with a powder is vibrated in the transverse direction with a maximum acceleration greater than that due to gravity, the particles inside the container become effectively 'fluidised'. The amount of frictional interactions transmitted from the powder to the container as a result of the vibration is then a function of the average particle size and its distribution. This paper describes the design and development of a novel vibrating reed technique operating on the basis of the above principle for the measurement of average particle sizes. Typical resolution in size is between +/- 8 and +/- 20-mu-m in the 20 to 900-mu-m size range particles. Preliminary results are also reported which establish the potential of the device for use for particle size distribution analysis.
