An installation for conveying bulk materials with a conveyor belt (1), which can be moved from a loading station to an unloading station, which is constructed on its two sides with a multiplicity of mutually spaced support rollers (13) that can be moved along a support track (14), and which is guided over deflection drums (12) in the regions of the loading station and the unloading station, a device (2), by means of which the conveyor belt (1) is turned through about 180.degree., being provided after the deflection drum (12) situated in the region of the unloading station, and a device (2), by means of which the conveyor belt (1) is turned back through about 180.degree., being provided in front of the deflection drum situated in the region of the loading station (10). In this arrangement, each turning device (2) is formed by a support structure in the form of a hollow cylinder, arranged on the inside of which are two spiral guides (24), along which the support rollers (13) arranged to the side of the conveyor belt (1) can be moved, the two guides (24) lying approximately diametrically opposite one another and executing an angular rotation of about 180.degree. over the length of the support structure (Figure 2).
