Optical incoherent space frequency analysis

The method for obtaining particle size distributions using optical incoherent space frequency analysis is detailed in [209,210] and resulted in the development of a low price, robust, on-line dry powder measuring system, the Jenoptik PSl-Z, (Particle Sizing using Incoherent light) which covered 32 size intervals in the range 1.5 pm to 2 mm. This was later expanded to 0.7 to 2500 pm [211]. For particles smaller than 50 pm a dispersion nozzle had to be fitted. [Pg.572]

A personal computer (PC) controls the measuring arrangement. The evaluation algorithm in the PC calculates the ring intensity values of the percentage of certain particle size classes by comparison between measured values and predetermined theoretical values. The intensity values are converted into a size distribution by an iteration process. [Pg.573]

The apparatus and software are described in a paper on the application of this technique to the particle size measurement of bulk material [213] and control of a grinding process [214]. [Pg.573]
