We illustrate that the primary cause of breakage is due to inter-particle collisions, rather than particle-wall impacts, and provide a statistical mechanics model giving the number of collisions resulting in fragmentation. date: 2009 type: Study Group Report type: NonPeerReviewed format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/393/1/ESGI70_5.pdf identifier: Richardson, G. and Cooker, M. and Delaney, N. and Hanley, K. and Hjorth, P. and Mackey, D. and Mason, J. and Mitchell, S. and O'Sullivan, C.
