Abstract of the Disclosure A surface cleaner wherein abrasive particles are directed against a surface to be cleaned, after which the abrasive particles rebound into the cleaner and return for recirculation. Several features are involved. First there is provided an accelerator for the normally gravity flowing abrasive particles to accelerate the particles towards a batting wheel wherein the abrasive particles are spread over a greater depth of an associated batting vane. Some of the abrasive particles will not rebound entirely up into the machine for return to the abrasive particle supply chamber. Accordingly, there is provided a sepa- rate path for the weaker rebounding abrasive particles to return to the accelerator. The batting wheel includes a tubular hub into which one of the supporting bearings for the associated shaft is telescoped. This permits batting wheels of different widths to be util- ized. The vanes of the batting wheel are flat vanes having at their inner ends enlargements. The vanes slide through slots with enlarged inner openings in an axial direction for mounting and removal. The vanes can be removed from the cleaner through an opening in one of the side walls thereof after a cover plate has been removed. There is also a wear plate which con- trols in part the direction of flow of abrasive parti- cles from the batting wheel. The wear plate protects part of the housing and most particularly one of the housing seals with the surface being cleaned.
