Abstract (en)
[origin: EP0069875A2] 1. A method of sand-blasting wherein particulate ejecting medium ist delivered to a carrier gas stream, propelled and accelerated by said carrier gas stream, and ejected to the surface to be treated, wherein an additive gas stream carrying an additive substance, preferably water, is fed to said carrier gas stream, and wherein a feed conduit for the particulate ejecting medium is followed by a frustoconically tapered region, characterized in that said additive gas stream carrying said additive substance is fed to said carrier gas stream at a location in the frustoconically tapered region where speed and acceleration of the particulate ejecting medium are still low.
