Abstract
A separator for the separation of fibrous bark from core material of chopped or crushed stalks of a crop such as Kenaf having two or more hollow bodies for rotation on inclined axes, each having a perforated wall and upper inlet and lower outlet ends. Within at least one of the bodies is provided a plurality of longitudinally extending, circumferentially spaced baffles. With rotation of each body while downwardly inclined from the inlet to the outlet, a fibrous phase of the material is conveyed in turn to discharge from the outlet end of one body and conveyed into the inlet of another body, while a more solid phase is discharged through the perforated walls of the bodies.
