ABSTRACT:
A particulate media/fluid delivery system comprises a tank for containing a supply of particulate media, preferably an abrasive powder. A modulator is disposed upstream of the tank for modulating the pressure of air flowing therethrough. A mixing chamber is adjacent to the tank, and an orifice is provided for delivering particulate media from the tank into the mixing chamber. A fluid inlet delivers fluid from the modulator to the tank, and a bypass tube is disposed adjacent to the fluid inlet for receiving fluid from the fluid inlet and delivering the fluid into the tank. A discharge port is provided for delivering a fluid/particulate media mixture to a tool. Control of the fluid/particulate is via differential modulation pressure. This differential modulation pressure is a function of two mechanisms, namely, the modulator in the system, including bypass (or blend) air around it that is metered, and the aforementioned bypass tube. Fine adjustment of the particulate media/fluid ratio is by a panel flow control valve, which may be either manually or automatically controlled, and coarse adjustment is via change-out of the bypass tube with another bypass tube having a different internal diameter.
