Breakage of Powders in Lean-Phase Pneumatic Conveying: The Influence of Material Type

By B.A. Kotzur, R.J. Berry, M.S.A. Bradley, and R.J. Farnish – Lean-phase pneumatic conveying is utilised across a wide range of industrial processes. This conveying method offers a number of advantages such as process hygiene and routing flexibility, however, due to high impact velocities in the pipeline, particle attrition remains a considerable issue. This work looks at how different material types respond to equivalent impact conditions, namely amorphous (Carbolux) and crystalline (cooking salt) morphologies, and translates this to expected behaviour during conveying. A bespoke bench-scale centrifugal attrition tester was used to test an individual particle size fraction of each material across two impact angles and five impact velocities. It was found that the percentage mass retained in the size fraction reduced linearly with velocity for the amorphous material, and polymerically for the crystalline material.

The chain of CHoPS conferences was started in 1995 in Israel. The first three were national conferences and took place in Herzeliya (1995), Jerusalem (1997) and the Dead-Sea (2000). Since they attracted many international participants, it became an international event that take place every three years. Since then four events took place in Budapest (2003), Sorrento (2006), Brisbane (2009) and Friedrichshafen (2012). Now, at the age of 20 years, when CHoPS become a leading scientific conference on handling and processing of bulk solids, it returned to visit Israel again.

The conference was aimed to bring together scientists and industrialists to exchange knowledge and ideas. It  covered all topics of particle technology and therefore enabled the participant not only being updated with recent developments and investigations in their fields of expertise, but also to be enriched with related topics. In order to do that, the program had four parallel oral sessions as well as poster sessions. Moreover, as is tradition in CHoPS conferences, many plenary and keynote lectures from international experts on various topics were presented.
