Abstract of the Disclosure: A vibration barrel grinding device, particularly for use with light articles, has an outer peripheral wall of the barrel forming a toroidal-shaped tub. Such peripheral wall extends up to an abruptly inwardly extending wall portion to force the grinding mass inwardly. A cylindrical core is mounted, either fixed or rotatably to form the, inner peripheral wall of the barrel and a number of blades are provided on the core, these blades being inclined downward so that the flow of the grinding mass is forcibly moved downwards to improve the grinding efficiency.
