    摘要： A study was done to compare the performance of a conventional V-blender to a V-blender that incorporates perturbations of the particle flow by rocking the mixing vessel during its normal rotation. Mixing was investigated using glass beads with sizes from 66.mu. to 600.mu. in vessels of approximately one liter volume. Mixture uniformity was assessed qualitatively, using two different methods. One method involved a transparent mixing vessel where it was possible to see particle flow patterns and assess the state of the mixture at its surface during the entire experiment. The second method involved disposable aluminum mixing vessels, where the mixture was solidified by infiltrating the mixture with a binder. By slicing the solidified structure, it was possible to assess the entire state of the mixture including its interior structure after the completion of each experiment. Mixture uniformity was also assessed quantitatively using image analysis of the slices. For both particle sizes, the extent of mixing was greatly enhanced using the rocking V-blender compared to the conventional V-blender.

    摘要： A method and apparatus enables testing of sifting segregation of a particulate solid mixture in a storage bin or hopper. The apparatus makes use of a convergently and divergently angled hopper for collecting the mixture. The apparatus further makes use of a minimally-shearing feeder mechanism supplying a desired flow of mixture, with minimal to no sifting segregation, to the angled hopper. A collection mechanism removes samples of the mixture from the angled hopper for analysis with minimal disruption of the particles of the mixture relative to each other. Thus, samples resulting from the testing apparatus, and corresponding method, are highly representative of mixture conditions within a larger storage hopper.
