inadequately functioning Sandblasting nozzles can result in blasting issues and excessive media consumption. Use a bore gauge or drill bit to inspect it for signs of wear or damage and wear and tear. Size matters when it comes to pressure and blast pattern; an increase in nozzle size increases productivity but may increase both air and abrasive consumption.
Long Venturi Nozzles
Nozzle bore shape plays an integral part in creating the blast pattern and velocity. Sandblasting nozzles come in two varieties – straight bore or venturi-shaped. Straight bore nozzles offer tight blast patterns for spot blasting applications and are typically found in small blast cabinets, while venturi shaped nozzles produce larger blast patterns with increased velocity at any given air pressure, leading to greater productivity with reduced abrasive consumption rates.
Size of Nozzle for Abrasive Blasting Applications depending on the type and size of abrasive, different sizes of nozzles will be necessary depending on its purpose and purpose of blasting action; finer materials, like sand, require smaller nozzles than coarser types such as steel shot. Pressure levels used also play an integral part: too much could damage surfaces being blasted; too little could leave inadequate blasting action taking place.
Long venturi nozzles feature a long tapered converging entry, short flat straight section and wide diverging exit for optimal productivity. Their venturi design accelerates and distributes abrasives evenly while increasing productivity by up to 40% compared to straight bore nozzles for similar abrasive use. Their heavy-duty construction includes tungsten carbide linings, natural rubber jackets and deep machined threads making these heavy-duty blast nozzles suitable for physically challenging blasting applications.
Short Venturi Nozzles
Orifice size dictates how quickly air and abrasive are consumed through nozzles, so referring to an abrasive consumption chart will help you select an ideal nozzle for your application. Nozzles come in 1/16-inch increments for measurement – if a drill bit fits easily through your current one it should be replaced immediately!
Sandblasting nozzles typically feature either a straight bore or Venturi-shaped bore for optimal performance. A straight bore creates an effective spot blast pattern ideal for spot blasting and cabinet work while Venturi bores accelerate and spread the abrasive blast for increased productivity.
When choosing a nozzle, take into account your available blast machine capacity in cubic feet per minute (cfm), the inside diameter of the blast machine piping, as well as your blast and air hoses. All components should fit together optimally for best performance – too large of a nozzle requires excessive air volume while too small may result in low blast pressure or premature wear on your blast hoses.
Once the appropriate nozzle has been chosen, attach it to its holder. Threaded nozzles with 1-1/4-inch threads attach directly with standard quick-coupling liners (or pins if using other couplings). After all of the components have been properly aligned and the operator points their Sandblasting nozzles at the surface to be cleaned before pressing their remote control handle for blasting action to begin blasting action.
