Title:
CRUSHING ROLLER, SOLID FUEL CRUSHING DEVICE AND MANUFACTURING METHOD OF CRUSHING ROLLER
Document Type and Number:
Japanese Patent JP2023092829
Kind Code:
A
Abstract:
To suppress abrasion of a roller part when being used in a state where the roller part is reversed, and lengthen a life of a roller part.SOLUTION: A crushing roller comprises: a toric roller part 49 which is engaged with an outer periphery part of a journal housing from outside and crushes a solid fuel between a crushing table and the crushing roller. The roller part 49 includes: a first part 49A; and a second part 49B which is arranged with the first part 49A in a line along an axial direction and fixed to the first part 49A. The first part 49A includes: a first proximal part 51A which is engaged with the outer periphery part of the journal housing from outside; and a first ceramic part 52A which is arranged on the outer periphery surface of the first proximal part 51A and excellent in abrasion resistance compared with the first proximal part 51A. The second part 49B includes: a second proximal part 51B which is engaged with the outer periphery part of the journal housing from outside; and a second ceramic part 52B which is arranged on the outer periphery surface of the second proximal part 51B and excellent in abrasion resistance compared with the second proximal part 51B.SELECTED DRAWING: Figure 3
