Dixon slugging classification

Powder Classification Techniques. The Geldart (1973) fluidization, and Dixon (1981) slugging classifications have been found useful in explaining ... 

The following comments are based on the findings of Wypych (1989b) who compared the actual conveying characteristics of several materials with the slugging classifications of Dixon (1979) and Dixon (1981). 

Classify the bulk solid according to the Dixon (1979, 1981) slugging diagram that matches the existing or proposed diameter of pipeline. Based on the research and consulting experience of the author, the following possibilities are proposed in relation to the Dixon (1979) classifications. 

For a product that is well contained inside a particular group (i.e., A, B, C or D), the Dixon (1981) slugging diagram and classifications generally provide a good initial indication of what to expect when the product is conveyed in the dense-phase mode. 

Classiflcations of Fluidization Behavior Geldart [Powder Technology, 7, 285 (1973)] and later Dixon [Pneumatic Conveying, Plastics Conveying and Bulk Storage, Butters (ed.). Applied Science Publishers, 1981] developed a classification of fluidization/aeration behavior from studies of fluidized beds and slugging in vertical tubes.
