Abstract

The present invention provides an improved abrasive delivery system for delivering an abrasive material to a waterjet cutting nozzle which has no external pressure effects on the orifice metering the flow of abrasive material from a container for the material by using air pressure to transport the abrasive material to the cutting nozzle through a standard metering orifice where equal pressure is maintained above and below the orifice to provide a constant volume of abrasive material flow to the cutting nozzle which is located up to 100 feet or more from the metering device.
