Abstract: A regeneration device configured for foundry sand reconditioning, having a cylindrical container having a cover and a bottom, wherein the container has a first opening and/or a second opening, and a plurality of rotationally driven friction elements formed in the container. The friction elements are arranged on a first shaft, and a first bearing is formed on the first shaft. The first shaft has a second bearing spaced apart from 1 he first bearing. The friction elements are arranged between the first bearing and the second bearing. The container has a first flange on the upper side and a second flange on the lower side, wherein the first flange is force-locked to the cover, and the second flange is force-locked to the bottom.
