Marine Water Sand Blasting Machine

There are two commonly used methods of marine water sand blasting machine: compressed air and wet sandblasting. The latter is the safer of the two. Compressed air sandblasters require the operator to wear protective clothing and breathing protection during use. This is not necessary through wet sand blasting unit which uses high-pressure power washers to achieve similar results. Additionally, the process of wet sandblasting produces to contaminating dust, making it safe for use in or around shipyard, marine, Anti-corrosion engineering, etc
The angle of attack and distance from the work surface may be varied to provide the best work speed, while still maintaining the greatest amount of impact energy. For optimum performance the sand inlet hose should not exceed 5 meters
When the sand unit is operating efficiently, there will be a smooth and continuous flow of sand through the nozzle. The amount of sand flow is directly related to the vacuum created in mixing nozzle. The intensity of the vacuum is dependent upon the liquid velocity of the water.

The pressure and flow rate through the spray nozzle are the factors that determine the liquid velocity, amount of vacuum and rate of sand flow.
If the spray nozzle is chosen to give the maximum pressure and flow rate possible for the pump, the rate of sand flow will also be at maximum. Total vacuum seal and maximum swirl velocity are obtained at 5º spray nozzle.

Because of the water ingredient, marine water sand blasting machine will not create any environmental pollution problem caused by fluttering the micro power.
It can remove the burrs (surface projections) & scales formed on surface and clean the surface without damaging the work piece.
The surface finishing can access a homogeneous matte finish (spot pattern). It can contribute significantly to the finishing demand for surface roughness.
It only applies small shot blasting effect to the surface to be finished and improve and reinforce the material of work piece.
The foreign materials after being removed will be rinsed and flushed out by the jet of water.
It doesn't require any chemical during operation.
It doesn't affect the dimensions of the object.

Though water consumption is not too high, it is to be taken in to account to dispose it off or recycled.
The surface roughness is more than dry sand blasting.
