Title:
CRUSHING ROLLER, CRUSHING TABLE, SOLID FUEL CRUSHING DEVICE, AND METHOD FOR PRODUCING CRUSHING ROLLER
Document Type and Number:
WIPO Patent Application WO/2024/096063
Kind Code:
A1
Abstract:
A crushing roller (13) comprises a journal housing (43) supported rotatably with respect to a housing, and an annular roller part (49) fixed to the journal housing (43) and crushing a solid fuel between itself and a crushing table. The roller part (49) has a base part (51) fixed to the journal housing, and a ceramic part (52) provided on the outer circumferential part of the base part (51), having a coefficient of linear expansion different from that of the base part (51), and having better wear resistance than the base part (51). The ceramic part (52) has first ceramics particles (52c) and second ceramics particles (52d), which differ in rigidity and toughness from the first ceramics particles (52c). The mixing ratio between the first ceramics particles (52c) and the second ceramics particles (52d) changes along the direction of a rotation central axis (C2).
