Prediction of Centrifugal Deliquoring For Changing Particle Composition

摘要

The influence of particle size distribution on mechanical deliquoring in the centrifugal field has been studied insufficiently until now. 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 has been studied. A second objective is to develop a procedure in order to minimize the necessary experimental effort to characterize materials with variable particle size distribution on filtering deliquoring in the centrifugal field has been 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 setting 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 the optimization of the mechanical deliquoring process by changing the particle size distribution.
