ABSTRACT
The influence of the particle size distribution on mechanical deliquoring in the centrifugal field is only insufficiently studied until today. The objective of this paper is to contribute to a better understanding of these influences. Based on well-known models the influence of the entire particle size distribution on filtering deliquoring in the centrifugal field is being studied. A second objective is to develop a procedure in order to minimize the necessary experimental effort to characterize materials with variable particle size distributions. In the case of a modification of the particle size distribution (for example, due to modified settings of upstream devices) a prediction of the deliquoring results in filtering centrifuges can be made. No further deliquoring experiments have to be performed. On the other hand, it is also possible to use this procedure for an optimization of the mechanical deliquoring process by changing the particle size distribution.
