尽管固体颗粒的混合是一个仍有许多需要学习的过程，但工业设备的设计者往往未能利用现有的知识，因此无法实现最佳结果。本文综述了描述、规定和测试混合物的方法。混合器的操作必须被认为是在混合和分离之间产生平衡。这些过程的机制进行了讨论，并建议，混合器可以分为隔离或非隔离。待混合的组分可以类似地分类，并且因此获得用于特定任务的混合器的选择指南：倾向于分离的材料不应放入“分离混合器”。最后，需要小心处理的混合物，以避免隔离进行了讨论。
Although the mixing of solid particles is a process about which there is still much to be learnt, designers of industrial plants often fail to take advantage of the available knowledge, so that the best possible results are not achieved. This review discusses the methods of describing, specifying and testing mixtures. The operation of a mixer must be regarded as producing an equilibrium between mixing and segregation. The mechanisms of these processes are discussed and it is proposed that mixers can be classified as either segregating or non-segregating. Components to be mixed can be similarly classified, and a guide to the selection of the mixer for a particular duty is thus obtained: materials that tend to segregate should not be put into a “segregating mixer”. Finally the need for care in the handling of a mixture so as to avoid segregation is discussed.
