The Roller Press Required Spreading Force Determination for Obtaining High-Quality Briquettes from Pulverized-Coal Waste of Blast Furnaces

Abstract:

The briquetted material and pressing surfaces force interaction is considered in the deformation center pressing zone. The investigated material is considered as an elastoplastic medium, described by rheological model: Bingham's body, which most fully reflects the physical medium under study properties. The material stress-strain state is divided into two stages: ideal-elastic and elastoplastic, each described by the obtained equation. Parameters of the force impact of the material on the pressure rolls depending on material physicomechanical characteristics and a press geometrical parameters are obtained.
