ABSTRACT:
The invention provides an abrasive blasting system in which water is entrained in the compressed air stream used to carry the abrasive to act as a damper to prevent dispersion of the abrasive and surface debris after impact of the abrasive on the surface being treated. The abrasive and water feeds are controlled on dependence on the pressure of the source of compressed air so that all feeds are effected equally by fluctuations in the pressure. An additive may be metered into the water and adjustments are provided for controlling the ratio of additive and water and of water to abrasive.
