Document Type and Number:
Japanese Patent JP2001523777
Kind Code:
A
Abstract:
Apparatus is disclosed for refining lignocellulosic material including a pair of refining elements facing each other for relative rotation to refine the lignocellulosic material passing through the refining gap between the refining elements. The refining elements include rows of projecting working pins with substantially circular cross-sections and strips projecting above the refining element surface and extending substantially circumferentially along the refining surfaces. The rows of projecting working pins are disposed at selected radial positions on the two refining surfaces so that they avoid contact with each other during relative rotation of the two refining surfaces.
