Nozzles For Sand Blaster

Quick Overview

The nozzles can be divided into common nozzles, high speed(double inlet) nozzles, long range(single inlet) nozzles,


45 degree angle nozzles and denim spray nozzles according to the function.

SKU: Nozzles For Sand Blaster

Details

A blast nozzle accelerates the air and abrasive as the mixture exits the end of the hose.

The taper and length of the nozzle's inlet and outlet determine the pattern and velocity of the abrasive exiting the nozzle.

The composition of the liner material determines its resistance to wear.

The main material of the nuzzle is:Boron carbide. Silicon carbide. Silicon nitride.

Tungstensteel carbide (Rockwell hardness of HRA sequence is 96,93,91.8,91), alumina ceramics, steel, etc.

The service life of the nozzle is related to the material ,the type of abrasive blasting abrasive used and the nozzle length.

Requirements for Operation
Nozzles are sized by the diameter of their orifices in 1/16-inch increments.

A No. 2 nozzle has a 2/16-inch (1/8-inch) orifice, a No. 3 nozzle has a 3/16-inch orifice, etc.

The size of the nozzle orifice determines abrasive and air consumption. Air consumption is measured in cubic feet per minute (cfm) at a given pressure.

When choosing a nozzle, consider the amount of available air in cfm, the capacity of the blast machine and the inside diameter of the piping,

and the blast and air hoses. For optimal performance, these elements must be compatibly sized.

If too large a nozzle is used, low blast pressure and rapid wear on the blast hose will occur.

If too small a nozzle is used, smooth media flow will be difficult to achieve.

Description of Operation 
The operator inserts the nozzle washer into a contractor-thread nozzle holder and screws in the nozzle, turning it by hand,

until it seats firmly against the washer.

With all related equipment correctly assembled and tested, the operator points the nozzle at the surface,

to be cleaned and presses the remote control handle to begin blasting.

The operator holds the nozzle 18 to 36 inches from the surface and moves it smoothly at a rate that produces the desired cleanliness.

Each pass should overlap slightly.

The operator must replace the nozzle once the orifice wears 1/16-inch beyond its original size.

Common applications

Is mainly used in oil drilling, aircraft, ships, cars, bridges, construction, railways and other engineering in the field of painting and denim fabric,

surface treatment. Hard alloy injection forming technology for the production of sandblasting, derusting, cleaning products, mainly used in ships,bridges,

chemical plant, container, water conservancy, machinery, piping, etc. large equipment and parts surface blasting and derusting,decontamination treatment.

Classification

The nozzles can be divided into common nozzles, high speed(double inlet) nozzles, long range(single inlet) nozzles,

45 degree angle nozzles and denim spray nozzles according to the function.
