The results of laser diffraction volumetric distribution measurements can be correlated to a reference method if needed, for example sieve and sedigraph analysis. There is a small difference compared to the particle size analysis measured by other methods, such as sieve analysis, but repeatability and precision over a wide particle size range are the most important features in process control applications.įurthermore, its speed, non-contact nature, and robustness against ambient conditions make laser diffraction ideal for on-line mineral slurry applications. Laser diffraction particle size measurementĪ significant advantage of laser diffraction is that it gives a consistent volumetric particle size analysis result without any external calibration. As it is not sensitive to entrained air in the sample, it can also be used in regrind circuits.
