energy balance

The influence of additive nature as well as its ratio on the rheological, tribological and technological properties of blends based on ultra-high molecular weight polyethylene has been determined. The energy costs impact in the polymer blends processing has been studied. It is shown that the rheological and tribological properties of the samples have a complicated dependence, which is determined by inhomogeneity of the system.

Filtration drying of grinded sunflower stems as the unit operation of the technological line for solid biofuel production has been proposed. Theoretical aspects of heat transfer processes during filtration drying have been analyzed. The effect of the drying agent velocity increase from 0.68 to 2.05 m/s on the heat transfer intensity has been established. The values of heat transfer coefficients have been calculated on the basis of the thin-layer experimental data and equation .
