Know How a Shot Blasting Machine Works

The technique that no metal industry owner can magnificence without is shot Blasting. It is used in almost every industry that uses metal such as aerospace, construction, automotive, foundry, rail, shipbuilding, and many more. It is used to clean, galvanize strength also known as shot peening, or to polish the metal surfaces. The process of shot blasting machine has become an indispensable aspect of the metal building and the steel structure industry. This blasting technique provides some major benefits for the protection and maintenance of steel and metal products. 

Advantages of Shot Blasting Machine

Removal of Corrosion: This is the most preferred technique for removing all forms of rust and corrosive materials for metal and steel surfaces without reducing the strength of the product and leaving its base unaffected. Typical builds of corrosive that develop on the surfaces are:

  • Rust
  • Chemical Stains
  • Mill Scale
  • Faded or Chipped Paint
  • Heat Treatment Scale

Preparation of Surface: This method of blasting is by far the most effective and most efficient process for preparing a metal surface before the painting or coating process is done. It provides high blast pattern accuracy, with an extremely powerful bond between the blasted surface and the protective coating. The technique helps in revealing any type of defects and errors. It also increases the lifespan and the endurance of any future coating. 

Environmental Reasons: This blasting technique is one of the only few options that provide environment-friendly options for the removal of corrosion and the preparation of surface:

  • The process involves the use of the only abrasion to clean the surface of the metal products
  • No chemicals are used during the entire process.
  • Acids too are not used at any time in the entire process.
  • The only required clean-up is of the physical pellets.
  • All the blasted steel or dust of media is blown away by a powerful vacuum and dust collector.
  • The process also provides the freedom and convenience of recycling the materials used in the process.

Technologies Used in Shot Blasting Machine

The blasting process involves the use of two technologies:

  • Wheel Blasting (Air Less Shot Blasting) Technique
  • Air Blasting ( Pneumatic Shot Blasting / Air Operated Shot Blasting)

Shot Blasting Machine Design

We use a roller conveyor shot blasting machine based on our experience. The models are available from the truck or directly driving feed rollers, can work, high efficiency, and worker operational safety. However, consider surface cleaning as well as steel profiles and structural parts.

We designed an opening device width, height 1700mm for customers' work information. A steel pipe with a diameter of 1520mm is fed at a time. To ensure complete coverage, use a projectile body.

Wear-resistant steel sheet clip installation in the sealing chamber at both ends to prevent projectile spill. To ensure that the work site is free of projectiles.

The roller spacing device is designed to 1000mm in order to ensure a carrying capacity of 1T/m. In addition, to ensure security, spacer rollers are installed to prevent rolling steel pipe rollers.

6 direct-attached blasting devices with 11kw motors are turned on and placed in steel rollers to 1.2-1.6m/min speed through the blasting zone. When the steel hanging out roller is tilted through the pipe, the steel pipe dumping projectile collects balls spiral, which aids in projectile recovery.
