Abrablast Rebar/TMT Bar Roller Conveyor Shot Blasting Machine

REBAR/TMT BAR ROLLER CONVEYOR SHOT BLASTING MACHINE

ABRABLAST Rebar/TMT Bar Roller Conveyor Shot Blasting Machine is designed to clean and prepare the surface of rebars and TMT (Thermo-Mechanically Treated) bars before applying epoxy coating or other surface treatments. By effectively removing rust, scale, and other impurities, this machine ensures superior surface adhesion, improving the durability and performance of the applied coatings. This machine is an essential tool for manufacturers in the construction, infrastructure, and steel processing industries where high-quality surface preparation is critical for corrosion protection and coating performance.

Operations :

  1. Efficient Surface Cleaning: The high-powered blast wheels remove rust, mill scale, and surface contaminants, preparing the bars for superior coating adhesion.
  2.  Consistent Cleaning: The roller conveyor system transports rebars and TMT bars through the blasting chamber, ensuring even cleaning along the entire length of the bar.
  3. Automated and Continuous Operation: With an automated conveyor system, the machine ensures continuous operation, increasing productivity and reducing manual labor.
  4. Adaptability for Various Bar Sizes: The machine is designed to handle different diameters and lengths of rebar and TMT bars, offering flexibility in production.
  5.  Abrasive Recycling System: The machine recycles the abrasive media for repeated use, minimizing waste and reducing operational costs.
  6. Dust Collection System: The integrated dust collector captures dust and fine particles generated during the blasting process, ensuring a clean working environment and compliance with environmental regulations.
  7. User-Friendly Control: The PLC-based control system with a touch-screen interface allows easy operation and precise control of the blasting parameters.

Finishing Process and Application :

  • Epoxy Coating Preparation:Prepares rebar and TMT bars for epoxy coating by cleaning the surface and ensuring proper adhesion.
  • Construction and Infrastructure Projects:Provides surface preparation for rebars used in reinforced concrete structures such as bridges, buildings, and highways.
  • Corrosion Protection:Ensures optimal surface cleanliness for bars that require corrosion-resistant coatings such as epoxy or galvanized finishes.
  • Steel Processing Plants:Used in steel mills and fabrication plants to clean rebars before further processing or coating applications.
  • Oil & Gas and Marine Industries:Prepares steel bars for heavy-duty protective coatings used in harsh environments like offshore platforms and pipelines.

How It Works

Rebars and TMT bars are placed onto the roller conveyor, which feeds them into the blasting chamber. The high-powered blast wheels throw abrasive media (such as steel shot or grit) at high velocity onto the surface of the bars, removing rust, scale, and other contaminants. The roller conveyor ensures that the bars are uniformly cleaned as they pass through the chamber. After blasting, the dust collection system captures and filters out the dust and debris, maintaining a clean workspace. The cleaned bars are then ready for immediate epoxy coating or further processing, ensuring optimal surface conditions for coating adhesion and corrosion protection.
