Filtration rates in roller pressing of fibrous materials

This article includes measures to improve the quality of electricity, reactive power sources, as well as various factors and circumstances affecting electricity. The technological processes of any production largely depend on the quality of electricity. In general, low electricity quality can be characterized as any changes in power supply. The result is a violation of the normal directions of the production process, damage to equipment, transformers, electric motors. Modern methods of improving its quality in the transmission and distribution of electricity are very numerous and significant. In parallel, the article studied the components of the power supply system in order to achieve high-quality electricity in order to improve the living conditions of the population and increase production efficiency.

Analytical dependencies are determined that describe the patterns of change in filtration rates in the squeezing area. It was established that the fluid filtration rate along the abscissa axis at the boundaries of the compression zone is zero, and inside the zone, it takes negative values. It was found that the fluid filtration rates along the ordinate axis are zero at the beginning of the compression zone; they increase to a maximum at a point lying on the line of centers, and in the zone of strain restoration, they depend on the angle that determines the position of the point where the fluid changes direction.

“…References [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] are devoted to mathematical modeling of the roll pressing process. Analytical expressions for the contact area of the rolls and specific pressure are determined on the basis of modeling the shape of the roll contact curves and the distribution patterns of contact stresses.…”

The influence of factors on the width of the roller contact and the specific pressure under roller pressing of leather is analyzed in the article. As a result of experimental studies, the dependences of the width of the contact area and specific pressure on the intensity of the load, velocity, and diameter of the rollers were determined. It was revealed that the parameter of the technological specific pressure on the hide in the contact zone increases with an increase in the intensity of the load, the speed of rolls, the width of the contact area, and a decrease in the radius of rolls. An analytical dependence of the residual moisture content of leather on the specific pressure was determined. It was established that with an increase in specific pressure, the residual moisture content of leather decreases and asymptotically approaches a certain value of the function.
