Abstract

Wear of the components of a pneumatic conveying system is one of the major reasons why such systems suffer unplanned maintenance. This would not be a problem if the wear lives of the components could be predicted with reasonable accuracy. However, our knowledge is not advanced enough at present. The problem of wear in such systems is a very complex one in which several phenomena have important parts to play, with the process being affected by properties of the surface, the particles and the flow as well as the system geometry. This paper includes a review and comparison of the research based on experimental work carried out on both industrial and bench sized equipment that has taken place. It is concluded that not of the mathematical models so far derived have been general enough to be used for all possible situations. Details of an experimental wear rig where the centrifugal effect is used to project particles at a series of targets being developed at the Wolfson Centre for Bulk Solids Handling Technology, University of Greenwich will be presented. This device has the advantage that a large number of specimens can be tested under identical conditions, simultaneously. A discussion of the intended work plan for this research will then be presented in conjunction with details of possible future developments for this project.
