Measurement of particle size distribution by the use of ...

2012-5-16  The measurement of solid particle flow while measuring the sizes of particles at the same time presents a difficult problem. One of the possible solutions in relation to measuring the solid particle flow is the use of acoustic emission signal (AE) generated on the impact of the solid particles against a suitably chosen obstacle. The paper discusses the possible use of the acoustic emission ...
