4. The Working Principle of Automatic Shot Blasting Machines

Automatic shot blasting machines adhere to a clearly defined procedure for optimal surface preparation. Here is a detailed explanation of their operating principle:

4.1 Positioning and Loading:

The item of work is placed on a conveyor system or inside a chamber.
The machine assures proper alignment and secure fixation for efficient cleaning.

4.2 Destructive Propulsion

The device activates a high-speed impeller, which propels abrasive projectiles or grits towards the surface.
The abrasive particles strike the surface with controlled force, removing contaminants and producing a profile with a textured appearance.

4.3 Dust Collection

During the blasting procedure, a substantial quantity of dust and debris is produced.
To maintain a clean working environment and safeguard the operators, automatic shot blasting devices are outfitted with robust dust extraction systems.

4.4 Abrasive Recuperation

These machines integrate an abrasive recovery system to reduce waste and enhance cost-effectiveness.
The system accumulates used abrasive particles, separates them from debris, and reuses them.

4.4 Surface Examination

After the blasting procedure is complete, the surface is inspected thoroughly.
Any remaining contaminants or flaws are identified and appropriately addressed.
