Numerical simulation of particle classification in new multi-product

In order to obtain the product in a specified range, classification has to be carried out repeatedly. It is very meaningful for the classifier to classify particles by different particle size ranges and obtain multi products (Wadenpohl, 2004). The solution to this problem brings new challenges to the design of traditional centrifugal classifiers.
