“…The physical properties and system characteristics as well as the size and shape of the single particles influence mass transfer processes and complex effects such as Marangoni convection can occur . In case of solid dispersed phases, particle breakage induced by crushing, grinding, pulverizing , and particle growth by agglomeration or crystallization are often investigated . Tab.…”

“…Single drop and bubble breakage in vicinity to dispersion units can be monitored by external cameras and particle tracking , . The breakage of solid particles can be investigated using single impact tests, pendulum apparatuses, drop weight tests and slow compression with subsequent particle size analysis, e.g., by sieving or microscopy combined with image analysis , , . The aim in all material systems (i.e., bubbles, drops and solid particles) is to find correlations between collision and energy, respectively, and the resulting number and size of daughter particles.…”

The experimental accessibility of disperse systems often is a critical factor when it comes to the development of modeling approaches that intend to converge towards an exact solution. Often, integral or pseudo‐homogeneous values are used to reduce the complexity of the system, but a detailed single particle or interface analysis is crucial to understand relevant effects that also affect the swarm behavior. A high number of experimental techniques with respective limitations and advantages is available to quantify these effects. In this work, an overview on measurement techniques for momentum, heat and mass transfer in particle swarms as well as for the particle size distribution and interface characterization is provided. The industrial applicability is addressed by pointing out the vicinity to the process and the costs of different measurement techniques.

“…The influence of coal strength by rank (thermal maturity) is shown in Figure 59 (Palmer et al, 2005cited in Deisman, 2016. This can be observed on the boundary from low to medium volatile bituminous up until the high volatile bituminous (Stach et al, 1982;Medhurst and Brown, 1998;Palmer et al, 2005;Esterle, 2008;Deisman, 2016), which is evident in tests such as Hardgrove grindability index and hardness (Ting, 1977;Stach et al, 1982;Hower et al, 1987;Hower and Wild, 1988;Narayanan et al, 1988;Van Krevelen, 1993;Conroy, 1994;Barton et al, 1994;Klawitter et al, 2015).…”
