Abstract
A water pump is connected to a mixer so as to blast high pressure water at a high speed in the mixer. The air and powder are supplied to the blast flow of the high pressure water through an air supply pipe and a powder supply pipe respectively so that a mixture flow composed of the gas, the droplet-like fluid, and powder is formed. The mixture flow is blasted from a nozzle at a high speed so as to be sprayed onto a surface to be treated. Thus, impact actions held by the powder and the droplet-like fluid as cleansing/scraping media are given to the surface to be treated. Thus, a cleansing/scraping operation is achieved. Then, if the fluid, gas or the like supplied to the mixer is heated, the cleansing/scraping operation can be further accelerated.
