Particle Size Determination

The continuous monitoring of the particle size distribution in particulate processes with suspensions or emulsions requires measurement techniques that can be used as in situ devices in contrast to ex situ or laboratory methods. In this context, for the evaluation of turbidimetric spectral measurements, the application of different numerical inversion algorithms is investigated with respect to the particle size distribution determination of polystyrene suspensions. A modified regularization concept consisting of a Twomey-Phillips-Regularization with an integrated nonnegative constraint and a modified L-curve criterion for the selection of the regularization parameter is used. The particle size (i.e., particle diameter) of polystyrene suspensions in the rangex=0.03–3 µm was validated via dynamic light scattering and differential centrifugal sedimentation and compared to the retrieved particle size distribution from the inverted turbidimetry measurements.

Abstract The cut size determination on the basis of proposed matrix model of classification process in a centrifugal air flow classifier with a fluidized bed is presented using matrix model. The presented methodology of cut size determination is based on the precise measurement of the total mass of fed material and coarse product in experimental tests. Knowledge of the feed particle size distribution is also required. Considered classifier is a part of the fluidized bed jet mill. The presented cut size determination will allow to optimize mill work and prediction of particle size distribution of the classification products.
