“…In this case, part of the applied pressure, and, as the spin is performed, the proportion of pressure perceived by the liquid decreases [21]. Moreover, under squeezing and compaction, the proportion of pressure perceived by fluid decreases, while that of the solid phase increases.…”

“…In [19][20][21][22][23][24], the residual moisture content of wet material was determined considering the phenomenon of contact interaction in the squeezing zone, that is, by jointly solving the problem of contact interaction and moisture filtration. However, these models are too complex for practical use, and they also use empirical dependencies obtained experimentally.…”

This paper presents the results of an efficiency analysis on the pressing of leather after dyeing, determined by the residual moisture content of the leather. The study establishes the law of changes in humidity during the leather pressing process. It was found that as the thickness and initial moisture content of the skin decreases, its final moisture content also decreases. An analytical dependence of the residual moisture content of the skin has been derived, which can be used to determine rational parameters for squeezing machines. The results show that reducing the skin thickness and increasing the roller radius lead to a decrease in the residual moisture content of the leather.

Calculation formulas for determining the energy-power parameters of roll mechanisms, such as the forces created by the roll gripping devices, the torque, and the power required to rotate the rolls were derived in the study. It was revealed that the radii of the rolls and the thickness of the processed material have the greatest influence on the energy-power parameters. Reducing the roll radius and material thickness makes it possible to reduce the gripping force related to a decrease in the length of the contact zone. As the radius of the roll decreases, the torque decreases as well due to the decrease in the radius of action of the resulting friction force.

Force analysis of roller squeezing mechanisms was conducted on the basis of analytical dependencies obtained to determine the energypower parameters of roller squeezing of semi-finished leather products after dyeing. These dependencies were determined taking into account the hydraulic pressure during squeezing. It was revealed that the thickness of the leather layer and the radius of the roll have the greatest influence on the energy-power parameters. With a decrease in the thickness of leather and the radius of the roll, the gripping force can be reduced due to a decrease in the extent of the contact zone. A decrease in the roll radius reduces the torque and power required to rotate the roll.
