Sand Blaster Nozzle

A Sand blasting Nozzle life is very hard for one to predict accurately because of the many features such as the vast range of abrasive media being used, their sizes, their different shape, their hardness, varying air pressure coming at the nozzle for sand blasting machine, The Sand blasting nozzle tips bore size and sand blaster nozzle mouth diameter during blast hose life, methods of abrasive media cut-off or machine shut-down. Sandblasting Nozzle size is of varying shapes used to blast different patterns on the blasting surface.

When selecting a nozzle for sandblasting, there should be a balance to be kept in mind, and it starts with our air compressor (sandblast nozzle air consumption). Once we understand how the size of our compressor for sandblasting nozzle air consumption affects production capabilities, then we will look at tungsten carbide nozzle size.

The next consideration is the sandblasting nozzle size & shape. Sand blasting nozzle types are mainly two shapes straight bore and venturi nozzle, venturi sand blasting nozzle is with multiple sizes found with various different patterns. Lastly, we want to consider the material from which the nozzle is made of. The three main factors in selecting the ideal air blast nozzle for sandblasting bore material are durability, impact resistance, and price.

The more air volume compressed per minute, the higher is the pressure produced at the air blast nozzle. This improvises the production rate in two ways:

  • High pressure increases the velocity of abrasive media particles, delivering more kinetic energy upon the surface blasting, imparting a deeper anchor pattern. This allows us to use a finer grade of abrasive media, which produces more impacts per volume on blasting surfaces.
  • More air capacity allows us to use a bigger bore of the nozzle for sandblasting, which lets us put more abrasive material on the target surface.

Sand blasting Nozzle Size

For sand abrasive blasting, the most commonly-used air blast nozzle orifice sizes range from 3/8″ inner diameter to 3/4″, increasing by increments of 1/16″. An 8mm air blast nozzle is constructed to generate pressure at a 120 CFM air compressor. A 10 mm sandblasting nozzle is enough to generate an effective blasting pressure at 210 CFM air compressor.

It’s important to notice that when we double the diameter of the orifice, we quadruple the size of the orifice and the volume of air and abrasive media that can pass through the sandblasting nozzle.

To find our optimally productive sandblasting nozzle, determine what nozzle pressure (PSI) we need to maintain for productive blasting, and sandblast nozzle air consumption or what volume of air our available air compressor can supply per minute (CFM).

Types Of Sand Blasting Nozzle :

Sandblasting Nozzles are of two basic shapes: straight bore and Venturi, with several different variations of venturi, sand blast nozzle.

Straight Bore blasting Nozzle

As compressed air enters the converging (left) end of a straight bore nozzle it accelerates, accelerating the abrasive media particles suspended in the flow. These abrasive media particles exit the nozzle in a tight stream and produce a narrow, concentrated blasting pattern upon the impact surface.

Venturi Nozzle blasting Nozzle

Blast Pattern: 3″ at 18″ distance
Production Rate: 4.5/5

Venturi nozzles have a converging entry and a diverging exit. This shape is designed to produce an effect that greatly accelerates the airflow and media particles.

The Venturi effect is an observation that when an airflow accelerates while passing through construction, there is a corresponding drop in pressure level.

Besides producing a tremendous acceleration, the angled shape nozzle of the diverging end spreads out the flow, producing a large blast pattern and a more uniform particle distribution than a standard bore nozzle.

Long Venturi nozzles give up to 40% better production rates and consume less abrasive material compared to straight bore nozzles.

Double Venturi Blasting Nozzle

Blast Pattern: 3″ at 18″ distance
Production Rate: 4/5

A double Venturi nozzle is with an extra-wide exit opening and holes at the diverging end.

According to the Venturi effect, as the velocity of the flow increases, the pressure drops, creating a vacuum between the shockwave and the throat, reducing abrasive material velocity.

Wide Throat Blasting Nozzle

Blast Pattern: 3″ @ 18″ dist.
The Rate of Production: 5/5

Broad throat nozzles are a broad throat and an extra-1/4 inch wide converging section. When used in coincidence with a hose pipe with matching inside diameter (and with a corresponding air volume increase), the wide throat nozzle can improve productivity level up to 15% over a long Venturi nozzle.

XL Performance

Blast Pattern: 5″ at 48″ distance
The Production Rate: 3/5

These are extra-long nozzles accelerating media particles over a longer distance, achieving higher exit velocities, allowing the blaster to stand further back from the surface being blasted, and producing a larger blast pattern and higher production rates.

Sand Blast Nozzle Material

The third consideration while choosing a nozzle is the material of the lining inside the bore. More active materials will be more resistant to wear, but are more valuable to replace and are prone to cracking under rough handling. There are two basic types of nozzles and their details.

  • Tungsten carbide nozzle
  • Boron carbide nozzle

Tungsten Carbide Nozzle

Durability: 1/5
Impact Resistance: 5/5
Price: Low

This tungsten carbide nozzle is the least durable of the carbide nozzles, but relatively less costly and resistant to impact. Mostly suitable for blasting with copper slag, glass, and mineral abrasive media.

Boron Carbide Nozzle

Durability: 3/5
Impact Resistance: 1/5
Price: High

Boron carbide nozzle is extremely hard and durable, but brittle in nature. It can give up to ten times the longevity of tungsten carbide.
