| Abstract: |
This thesis covers an investigation into the topic of size control in pel-letisation, with a focus on how it relates to the pelletisation of ferrous by products. The ferrous by product of focus is oily mill sludge, which has had its properties examined. The kinetic behaviour is also examined using Discrete Element Methods. Over the course of the investigation the growth behaviour of granules has been clarified as being able to be explained en-tirely through external saturation sources such as spray and consolidation behaviours. These contribute to the cohesion of individual pellets, and adhesion of pellets together, which constitute a completely new model of agglomeration. This Adhesion-Cohesion model is physically in line with agglomeration research and granular mechanics as a whole, and was subse-quently integrated into a Discrete Element Method simulation of agglom-eration which provided validation for the growth behaviour predicted. |
