Influence of friction force in the port of screw of granulator upon variation of temperature of grained product

Abstract

Investigate the effect of the frictional forces on the temperature change of the plasticized fodder mixture during its movement along the channel of the propeller granulator. Methods. Continuous media mechanics, thermodynamics and integral calculations. Results The dissipation of mechanical energy for the work of screw feed granulator with variable geometric parameters of the propeller is considered. Conclusions As a result of theoretical studies of the process of the movement of plasticized feed in the channel of the propeller of the feed granulator, an expression was obtained of the change in its temperature due to the work of frictional forces on the material of the working organs of the granulator.
