Abrasive element support with self-sucking device and method for removing grinding particles

Abstract

An abrasive element support having an axis of rotation and a fastening surface for attachment of an abrasive element is designed as a self-sucking device in the form of a radial fan device. The fastening surface has a fastening element such as a hook and loop fastening element that allows passage of grinding particles in a direction parallel to the fastening surface. The radial fan device has intake and exit openings, wherein the intake opening is arranged closer to the axis of rotation than the exit opening. The intake and exit openings communicate through at least one acceleration chamber of the radial fan device.
