The feed section capacity calculation determines the volumetric and mass throughput of a single-screw extruder operating as a drag-induced solids conveyor. It balances geometric channel displacement with bulk material properties and empirical filling and slipping efficiencies to size equipment and prevent feeding instabilities. Accurate capacity estimation ensures consistent processing without starving or overloading the extruder.
