Title:
REFINER FOR BEATING LIGNOCELLULOSE MATERIAL AND REFINING SEGMENT FOR SUCH REFINER
Document Type and Number:
Japanese Patent JP2021080620
Kind Code:
A
Abstract:
To provide a refiner enabling more smooth flow and efficient pulverization or beating motion of a material.SOLUTION: A refiner segment is assembled with a first segment (30) and a second segment (31), wherein the first segment (30) is constituted so as to be used with a rotor disc for a refiner of a lignocellulose material, the second segment is constituted so as to be used with a stator disc for the refiner of a lignocellulose material, the first and second refining segments (30;31) are assembled with a projection structure for pulverization of the lignocellulose material, and a height H of the projection structure of the first refining segment (30) is at least 3-fold higher than a height H* of the projection structure of the second refining segment (31).SELECTED DRAWING: Figure 4
