How does a mesh belt shot blasting machine work?

Mesh belt shot blasting machine is a kind of equipment commonly used for metal surface treatment, especially for cleaning and removing oxide layer, rust, oil and other impurities, and improving the surface roughness of workpiece to enhance coating adhesion.

Working principle of mesh belt shot blasting machine:
Mesh belt conveyor system: The core feature of mesh belt shot blasting machine is the mesh belt conveyor system, which can automatically convey the workpiece into the shot blasting room. The mesh belt is made of metal or wear-resistant material and has good durability. The mesh belt can adjust the speed as needed to ensure that the workpiece passes through the shot blasting area evenly.
Shot blasting process: There are one or more high-speed rotating shot blasting wheels in the machine, which use centrifugal force to spray shot (such as steel shot, steel sand, etc.) at high speed onto the surface of the workpiece. These high-speed impact shot will remove impurities, rust, oil, etc. on the surface of the workpiece, and form a certain roughness on the surface of the workpiece, which is helpful for subsequent coating adhesion or welding process.
Surface treatment: The shot blasting machine can achieve different surface treatment effects by adjusting the speed, angle and type of shot blasting wheel. For example, cleaning impurities, removing oxide scale, improving surface roughness or providing an ideal attachment base for coating.
Recycling and screening system: The shot after shot blasting is recovered through the collection system, and the inappropriate impurities are cleaned out through the screening device to ensure that the shot can be recycled. This not only reduces the waste of shot, but also reduces the operating cost.
Exhaust and dust removal: During the shot blasting process, due to the impact of the shot, a certain amount of dust or particles will be generated on the surface of the workpiece. The mesh belt shot blasting machine is equipped with a dust removal system to keep the working environment clean by inhaling and filtering particles in the air.

Workflow description:
The workpiece enters the shot blasting machine through the mesh belt.
The shot blasting wheel sprays the shot at high speed onto the surface of the workpiece.
The shot hits the surface of the workpiece to clean impurities or improve the surface roughness.
The cleaned shot is reused through the recycling system, and the filtering system removes waste.
Finally, the workpiece is processed and ready for subsequent processes such as painting or welding.

Advantages:
Efficient processing of large workpieces: mesh belt shot blasting machines are particularly suitable for long, large-sized workpieces, such as steel plates, steel pipes, etc.
High degree of automation: the use of automatic mesh belt conveyor can improve production efficiency and reduce manual operation.
Energy saving and environmental protection: the recycling and filtration system reduces the waste of shot materials and effectively controls dust pollution in the working environment.
Mesh belt shot blasting machines are commonly used in industries such as steel, shipbuilding, machinery manufacturing, and automobiles, and are very effective for workpieces that require surface treatment.
