摘要

In powder technology most of the techniques used for blending, mixing and homogenization are based on use of mechanical devices and flow differences. The result of such a blending/mixing method arises from a random process, mostly time dependent. At Delft University of Technology, (sub faculty Mechanical Engineering, section Bulk Materials Handling) research is done on a different technique to achieve a certain rate of homogenization. For this no mechanical devices or flow differences, are used to turn over the powder several times. The method is based on systematic input and output of powder and bulk materials in a flat bottom silo. In this paper an overview of existing mixing, blending and homogenization methods for up to 100.000 m~3 of buffer storage capacity is given. For this it is necessary to make a distinction between terms like: mixing, blending and homogenization. Furthermore the method of systematic homogenization in flat bottom silos is explained. Special attention will be paid to suitability of methods in terms of powder characteristics. E.g. one of the advantages of the systematic homogenization is the suitability for both free flowing and cohesive powders. The paper ends with an outline of future research at Delft University of Technology concerning systematic homogenization in mammoth silos.
