ABSTRACT:
A device for mixing compressed air and abrasive and providing the air/abrasive mixture to a delivery gun for use in artistic abrasive blasting. The device is provided with a vessel having an upper chamber for holding abrasive. Compressed air is supplied to a head space located in the upper chamber above the abrasive. An air delivery line extends from the head space to a mixing chamber located below the upper chamber in order to supply compressed air thereto. An adjustable mixing valve admits abrasive from the upper chamber into the mixing chamber where the abrasive is mixed with the compressed air before it exits the mixing chamber on its way to the delivery gun.
