Nozzle & nozzle holder is the most important working piece in sandblasting hopper, and an appropriate or inappropriate blast nozzle will affect the production rate. The taper or narrow and length of the blasting nozzle's inlet and outlet affects both the structure and velocity of the abrasive blasting media exiting from the nozzle. sandblasting nozzle and nozzle holder used in portable sand blasting machine, pressure blasting cabinet. The blasting nozzle is available in two types of basic shapes are straight bore and venturi have different variations of ventures of sandblasting nozzle.
Nozzle holder used in sand blasting machine to hold the blasting nozzle and connect it which blasting hose. Nozzle holder having threads on both sides. One side of threads is used to fit the nozzle into the holder and the other side threads are used to connect the blasting hose with the holder. One side threads size is the same for all sizes of the nozzle and the other side of threads which is used to connect the blasting hose is depends upon the outer diameter of the blasting hose.
| Nozzle Holder Size | Blasting Hose Size |
| NHP 3/4 | Fits a 33 mm outer diameter hose |
| NHP 1 | Fits a 38 mm outer diameter hose |
| NHP 2 | Fits a 38 mm outer diameter hose |
| NHP 3 | Fits a 54 mm outer diameter hose |
The sandblasting nozzle is available in many types and differentiates according to its shape, size, and working output.
Straight bore blasting nozzle in which compressed air enters through the converging left side of the straight bore nozzle is accelerating the abrasive media or particle suspended in the flow. These abrasive media particles are exit the nozzle's tight stream and create a narrow path, concentrated or silent blasting pattern upon the impact surface. The advantages of a straight bore blasting nozzle are ideal for smaller jobs, parts cleaning operations are easy and it can clean handrails. Easy to operate.
The venturi nozzle has a converging entry and a diverging exit. This shape is meant to supply an impact that greatly accelerates the airflow and media particles. The venturi effect is an airflow accelerates while passing through construction, there is a corresponding drop by pressure. Besides producing an incredible acceleration, the angled shape nozzle of the diverging end spreads out the flow, producing an outsized blast pattern and a more uniform particle distribution than a standard bore nozzle. The venture nozzle for vapor abrasive blasting, the most commonly used nozzle orifice sizes are available range from 3/8" inner diameter to 3/4", increasing by increments of 1/16". The blast pattern of the venture 3" to 18" distance.
A double venturi nozzle is double as compared to a venturi blasting nozzle with an extra-wide exit opening and holes at the diverging end. According to the double venturi effect, as the velocity of the flow increases, the pressure drops of creating a vacuum between the shockwave and throat of the double venturi blasting nozzle, reducing abrasive material velocity. The blast pattern of the venture 3" to 18" distance.
The wide throat is also called a Broad throat nozzle is a broad throat and an extra-1/4 inch wide converging section. When used with a hosepipe with matching inside diameter (and with a corresponding air volume increase), the wide throat nozzle can improve productivity or manufactured level up to 15% over a long Venturi nozzle. The Blast pattern of the venture 3'' to 18'' distance.
These are extra long nozzle which accelerating the abrasive media like copper slag, sand, abrasive garnet, steel shots, etc over a longer distance, achieving higher exit velocities. This nozzle allowing the blaster to stand further back from the surface being blasted, and producing a larger blast pattern and higher production rates. The blast pattern of the venture 5" to 48" distance.
