In this paper, the distribution of pressure on the bagasse layer in the sugar cane mills and an automatic regulation proposal to increase the efficiency in the extraction of sugar cane juice is approached. An analysis that considers the top shaft-roller as a beam on elastic foundation is carried out. It is possible to determine the pressure distribution on the bagasse layer and the mill bearing reactions. The behavior of the bagasse layer reaction is analyzed for different hydraulic pressures in each side of the mill; being demonstrated, an optimal relationship of pressures to achieve a uniform compression on the bagasse layer. The optimal hydraulic pressure rate is calculated with the help of the outlined method. Finally, once this pressure relation is known, a control strategy is developed for each hydraulic cylinder.
