ABSTRACT:
The cleaning apparatus includes a wheel in the form of a rapidly rotating drum having relatively few blades spaced circumferentially about the periphery thereof and extending radially thereon. Abrasive material is delivered from a hopper through a slot and is picked up by the blades of the rapidly rotating drum and delivered with extremely high kinetic energy into the surface to be cleaned. The apparatus is constructed so that the recovery path of the abrasive material from the surface to be cleaned and the delivery path of the abrasive material directed to the surface to be cleaned are in the same plane and in the same plane as the plane of rotation of the drum. The recovery path is generally contiguous with the housing of the drum, creating a compact apparatus which utilizes the normal path of movement of the recovered abrasive material. By providing an apparatus in which the delivery and recovery paths are both essentially in the same plane and in the plane of the rotating drum, the size of the apparatus required is reduced, wear on the components of the apparatus is significantly reduced, the construction is simplified and the cost is reduced.
