| Zusammenfassung: | This invention relates to spiral chutes in cylindrical casings which comprise sections (18) with gaps (16) therebetween spanned by extension portions (20) to compensate for movement therebetween. Two normal sections of the spiral chute are bridged in the region of the annular gap (16) between them by wear resistant plates (22, 24, 26) which overlap the annular gap from inside and form part of the spiral profile. |
