“…Previous work by Kantzas et al (2000) and Jonkers et al (1990) demonstrated that the application of the gamma-ray emission imaging technique could be extended to research in industrial processes such as fluidized beds where direct visual observation is precluded. Separately, they applied the gamma-ray imaging technique to study multiphase flow in porous media with ascertainable level of success.…”

The gamma emission imaging technique has been effectively applied for determination of the slurry radial flow pattern and mixing profile within the ball charge in a wet laboratory ball mill. Aqueous technetium, Tc99m radioisotope that emits 140 keV photons with a short half-life of 6.02 h, was utilized as a flow follower while the glycerol–water mixture was used to mimic the motion of the actual slurry as found in full scale systems. Tests were conducted under two different slurry viscosity conditions for two mill speed levels. Both qualitative and quantitative information of the slurry radial flow and mixing behaviour inside the mill were obtained. The slurry flow and mixing behaviour displayed a marked dependence on the mill speed and slurry viscosity. The slurry mixing time in the ball charge varied directly with the slurry viscosity but inversely with the mill rotational speed.

A review of existing and developing process tomographic different image reconstruction methods. Examples of existing, instrumentation suitable for characterising dry and wet partic-developing and proven applications are cited. Future needs and ulate systems is presented. Factors governing the selection of ways in which these needs can be met are suggested, including sensing techniques appropriate for static and dynamic imaging the use of multi-modality methods in which different types of of a wide range of single and multiphase particulate processes sensing methods are embodied in a single tomographic instruare discussed.
