Abstract

The results of the study of hydraulic pressure in the roll squeezing of wet materials are given. Mathematical models of hydraulic pressure distribution in the squeezing zone are developed. It is revealed that the hydraulic pressure in the compression zone increases from zero at the initial contact point to a maximum at a point lying on the line of centers. The distribution patterns of hydraulic pressure in the strain restoration zone depend on the length of its part, where the fluid flows from the wet material into the roll coating.
