Abstract
The dewatering drum 3 for devices for dewatering aqueous suspensions of solid material, particularly for sieve belt presses, has a closed shell 8. Profiles 9 are fixed to this closed shell 8 for forming shells 13 obliquely extending relative to the generatrix of the drum shell 8. The channels 13 deviate from the direction of the generatrix and extend either obliquely relative to the generatrix or are arranged in an arrow-like or arcuate manner, noting that the arrow tip or the culminating point 14 of the arc is showing in direction 11 of rotation (FIG. 3).
