Abstract
A method of delivering abrasive particulate material under pressure from a storage container adapted to contain the abrasive particulate material therein includes communicating an inlet valve with an inlet opening of the storage container and supplying a first gas, regulated to a first predetermined pressure, to the inlet valve. The first gas is released through the inlet valve and into the storage container, and a quantity of the abrasive particulate material is discharged through an outlet opening of the storage container to an output junction. In addition a second gas, regulated to a second predetermined pressure, is supplied to the output junction. As such, a pressurized supply of the abrasive particulate material is formed and delivered through the output junction.
