Abstract
A turbo-machine for transporting media loaded with solid particles includes a housing. At least one impeller is disposed inside the housing and defines impeller side spaces disposed between the impeller and the housing. Wall surfaces bound the impeller side spaces. The wall surfaces have various shaped protrusions, recesses, blades and grooves for conducting the flow of the medium near the wall at least partly into regions where the transport medium has a greater rotational motion.
