Using compressed air, the Fluidized Abrasive Delivery system creates an even distribution of abrasive flow that is essential to achieve reliable abrasive water jet cutting results. Compressed air uidizes and transports abrasive from a hopper to a single cutting head. Accurate metering and reliable on/off control of the abrasive is accomplished with a pneumatically actuated slide gate. An adjustment knob controls the slide gate opening for precise abrasive flow rates, and the indicating dial provides an accurate reference mark for the position of the slide gate.
