Material Flow in Rotary Drums
The experimental investigation of material flow in rotary drums is studied. An equipment in the size of pilot-scale was used to collect experimental data for investigation of validity of the conventional steady-state model of material flow in rotary drums. Also, the transient data of the time required for material movement in the empty drum up to any specified cross section are also reported. T...
متن کاملGlobal Life Cycle Paper Flows, Recycling Metrics, and Material Efficiency
Despite major improvements in recycling over the last decades, the pulp and paper sector is a significant contributor to global greenhouse gas emissions and other environmental pressures. Further reduction of virgin material requirements and environmental impacts requires a detailed understanding of the global material flows in paper production and consumption. This study constructs a Sankey di...
متن کاملnonlinear dynamic analysis of shells (material and geometric).
in this paper we have discussed the main features of a finite clement program which we have developed for nonlinear dynamic analysis of plates and shells with material and geometric nonlinear behaviour. for this purpose, initially, the finite element model which we have used is briefly described. afterwards, the nonlinear viscoplastic material model in one-dimensional and multi-dimensional medi...
متن کاملA dynamic probabilistic material flow modeling method
Material flow modeling constitutes an important approach to predicting and understanding the flows of materials through the anthroposphere into the environment. The new “Dynamic Probabilistic Material Flow Analysis (DPMFA)” method, combining dynamic material flow modeling with probabilistic modeling, is presented in this paper. Material transfers that lead to particular environmental stocks are...
متن کاملMaterial Flow Analysis for Identifying Rare Earth Element Recycling Potentials in the Eu-27
Rare earth elements (REEs) are essential for high-techology industrial sectors. This paper presents research on material flow analysis (MFA) applied to REEs in the EU-27. Innovative aspects of this research pertain to (i) considering potential lithospheric stocks of REEs in the EU and (ii) accounting for incomplete and imprecise information in MFA data reconciliation. Results obtained to-date p...
