ABSTRACT:
A mobile apparatus for treating substantially horizontal surfaces with particulate abrasive is provided with means for enhanced recovery of spent abrasive. Abrasive is propelled to the surface being treated at an angle such that particles rebound from the surface into a collection chute which attenuates the kinetic energy of the abrasive to facilitate recycling abrasive for reuse in the apparatus. Abrasive which is not recovered by its rebounding, passes to a rotating broom to be propelled into a collection bin for recycling for reuse in the apparatus.
