【発明の名称】交互に深溝を配したリファイナディスク
Document Type and Number:
Japanese Patent JPH09505364
Kind Code:
A
Abstract:
A disk especially suitable for a papermaking wood chip and pulp refiner has an array of refiner bars which protrude outwardly from a base member. Grooves are formed between adjacent bars which may change in depth toward the outer diameter of the disk. Alternating grooves are of greater depth, to increase the open area of the disk to facilitate steam evacuation without significantly reducing the bar stiffness and hence resistance to breakage and deflection of individual bars.
