Formatted abstract This thesis describes work carried out in the field of sugar cane crushing mechanics by the author. The forces acting in the direction of feed between the mill rolls and the approaching material are discussed. The measurements of roll surface pressure distributions by two independent experimental techniques are described. Equations are developed I in terms of stream function I which allow the juice flow pattern within the material in the region bounded by rolls t to be deduced. Predictions of pressure distributions are made from the resulting stream function surfaces and these are compared with those obtained experimentally. Measurements of feed and delivery pressures and of the natural feeding speed of the approaching blanket are discussed and conclusions are drawn. Theoretically predicted delivery pressure trends I calculated by analogue computation t are presented. Details of pressure-volume measurements for cane and bagasse of crushing experiments on ungrooved rolls and of shredding investigations are also given. Detailed mechanical and extraction results are tabulated for a large number of individual tests together with computed torque-load numbers I capacity numbers reabsorption factors and energy consumptions for these tests. General descriptions of apparatus designed specially for the various projects have been included. Full instructions for the preparation of data and methods of operation are provided for several specific and general purpose digital computer programmes.
