Tunnel type shot blasting machine profile

It also can named hook pass through type shot blasting machine
This type of cleaning machine is suitable for the surface cleaning of large and medium-sized castings, forgings and structural parts in casting, construction, chemical, motor, machine tool and other industries.

Tunnel type shot blasting machine application

We use shot blasting technology to achieve the purpose of derusting and strengthening, because shot blasting is still the most economical and reliable method in the world. Compared with other
cleaning technologies, shot blasting has the following advantages:
Improve the fatigue resistance of mechanical products and metal components
Eliminate stress concentration
Extend its service life
Optimizing the surface state of the workpiece
Greatly improve the cleaning efficiency
Reduce the labor intensity of cleaning up
Reduce environmental pollution
This type of equipment is widely used in machinery manufacturing, engineering machinery, mining machinery, pressure vessels, automobiles, ships and other industries to improve the appearance quality and surface process status of its product parts.

Tunnel type shot blasting machine working principle

Mechanical sand surface treatment is the use of high-speed rotation of the impeller, to clean the surface of work piece.
after a very short period of time (usually 5-7 minutes), to complete the entire cleaning process.
Technical parameters Hook pass through type shot blasting machine

Tunnel type shot blasting machine function

QT37 hook type shot blasting machine is a new type of equipment independently developed by our company. It is a non-standard product specially designed by our company according to customer requirements. It has the following advantages:

The use of 4-12 large-scale shot blasting volume and high shot speed of the international fourth-generation belt centrifugal shot blasting machine, significantly improves cleaning efficiency and obtains satisfactory cleaning quality.

The simulated projectile diagram (including the determination of the model, number and spatial arrangement of the projectile) is drawn in three dimensions using computer-aided design (CAD). The selection and arrangement of the projectile is more reasonable. The utilization rate and labor productivity of the projectile are improved, the cleaning effect is ensured, and the wear of the chamber body guard plate is reduced. The design of the equipment is completely done with CAD.

Separator adopts BE-type full-curtain type separator technology of American Pan Bangen Company, and the separation effect is good.

Workpiece cleaning adopts hook-hanging mobile pass-through cleaning, which has a high degree of automation and greatly reduces the labor intensity of workers.
