What is shot Blasting? What are the differences between shot blasting and sand blasting?

Shot blasting is a technological process of removal or elimination of impurities from various surfaces with abrasive. It is made use of as surface protection and for prior-preparation of surfaces before processing including colouring, welding, etc.

How the clean surface would finally look like will reply on a number of factors: the mass of the abrasive particle, the particle’s impactor angle, particle velocity, the particle shape, coverage and density of the strokes kg/m2

shot blasting is employed in different industries including metal manufacturing industry, automotive industry, aviation industry, foundry, manufacture of different welded structures, shipbuilding and also in making several silos, tanks, chassis, pipelines, just to name a few.

Differences between the process of shot blasting and sandblasting:
One of the primary differences between the processes of shot blasting and sandblasting is that in shot blasting throwing wheel is used, whereas, in the sandblasting process, generally compressed air is utilized.

shot blasting: abrasive is given acceleration via the throwing wheel, which turns in a steel housing, having a one-sided oriented opening. shot blasting is applicable for welded constructions, different profiles and blasting metals.

Sandblasting: this process is the dosing of the abrasive particles in a stream of compressed air and given rapid acceleration in the outflow via the blasting nozzle.  The process of sandblasting is applicable in the blast cabinets and blast rooms.
