Automatic Pendant Chain Type Shot Blasting System for Steel Components Cleaning

In the manufacturing of construction machinery, mining equipment, and heavy-duty transport vehicles, surface treatment for large welded structures and heavy workpieces has always been a challenging task. The overhead chain Shot Blasting Machine, with its robust load-bearing capacity and continuous operation characteristics, has become a reliable choice in this field.

First, there is the catenary shot blasting machine, which is like an aerial corridor. Through a variable-speed drive device, it lifts the workpieces and transports them at a constant speed through the cleaning area one after another. The workpieces are in a sealed cleaning chamber, receiving impacts from projectiles from multiple angles. These projectiles are accelerated to speeds of over 80 meters per second by the "heart" of the machine - the shot blasting device. The impeller inside the shot blasting device rotates at high speed under the drive of the motor, generating a powerful centrifugal force that throws the projectiles like a violent storm onto the surface of the workpiece, completely removing the sand, oxide scale and rust adhering to it.

After the impact is completed, the projectiles, the stripped impurities and the dust mixture fall through the bottom grille into the recycling system. The bucket elevator, like a vertical elevator, transports the mixture to the top vortex separator. Here, the intact projectiles, due to their higher density, are precisely selected and returned to the pellet storage bin for recycling, while the dust and debris are sucked into the dust removal system. After this "ritual", the workpieces are again blown by high-pressure air at the exit, and finally leave the system in a clean state, completing an efficient surface treatment.I. Application Scenarios: Batch Processing of Large Welded Parts and Structural Components

The overhead chain shot blasting machine is suitable for surface cleaning of heavy workpieces such as excavator booms, mining vehicle structures, large enclosures, and frames. Workpieces are continuously conveyed into the blast chamber via the overhead chain system, undergoing comprehensive treatment by multiple high-power blast wheels. This process completes the cleaning of complex structures in a single pass, significantly improving operational efficiency.
