This work reports the results of a systematic study of the factors that affect
the bridging behaviour of bagasse. It shows that traditional bulk solids theory
is inappropriate for predicting bagasse flow mainly because of the
impossibility of obtaining a reliable measure of internal friction. It
demonstrates the significant influence of fibre length and moisture content
on its handling charateristics.
Correlations of pertinent bulk properties such as compactibility, tensile
strength, surface friction and translation of vertical into horizontal pressure
have been developed. These were derived as a result of measurements in
equipment that was designed for the purpose.
Finally, an empirical model utilising these correlations is proposed by which
the likelihood of bridge formation in any piece of bagasse handling equipment
can be determined. The validity of the model is assessed by comparison with
bridging tests that were performed under controlled conditions. / Thesis (Ph.D.)-University of Natal, 1996
