The objects of the work were to provide much needed data on the physical properties of sugar cane and bagasse and to determine the effects of certain variables on the performance of an experimental, two-roll, sugar mill.
The density of the cane fibre, the "static" and "dynamic" pressure-volume relationships, the permeability, and the coefficient of friction have been measured. The importance of these physical properties on the performance of a sugar mill have been discussed in detail.
The feeding of the experimental mill has been thoroughly investigated and a theory of mill feeding was developed. The importance of a uniform feed blanket with a tensile property was demonstrated.
The effects of the variables, compression ratio, roll speed, cane preparation, and feed blanket depth on the juice extraction and the mechanical performance of the experimental mill have been discovered. Complete mechanical measurements were taken. A quantitative as well as a qualitative analysis of the effects of these variables was undertaken and their relative importance on the sugar mill’s performance has been established.
