Abstract

The sandblasting machine includes an underpressure sand tank (1) supplied with compressed air through a duct (8). At the lower end of the tank is a sand ejection chamber (13) containing a diaphragm (15) provided with a hole (17). A disc (18) is operable to selectively close this aperture and block communication between the tank and chamber. A compressed air pipeline (11) feeds the tank supply duct (8) and also supplies compressed air to the supply duct (21) of the ejection chamber. A pump (31) selectively supplies water into the ejection chamber supply duct (21), the wet or dry sand being ejected through a discharge duct (22).
