摘要：Spiral chutes, in particular outer spirals on bins, for downward conveying of bulk materials, such as hard coal, have, as seen in section, a chute throat and a vertical projection and an inclined or convexly curved region directed towards the eye of the spiral. In particular the chute throat is lined with tiles consisting of a highly wear-resistant material. For the purpose of economical saving of very expensive wear material while, at the same time, avoiding the destruction of adjacent tiles, the tiles are constructed as combination tiles (1) which can be laid in a mortar bed, ceramic elements (3, 5) consisting, for example, of oxide ceramic material being provided at least partially on a base plate (2) formed from high-quality concrete, and being adhesively bonded to the latter in a toothed arrangement (Figure 1). <IMAGE>
