What is Rebar Shot Blasting Machine with Surface Finish Level Sa2.5?
A Rebar Shot Blasting Machine with Surface Finish Level Sa2.5 is a specialized industrial device designed to clean and prepare the surface of steel rebar (reinforcing bars) for further processing, such as coating or welding. This machine achieves a surface finish level of Sa2.5, which means the surface will be free of visible oil, dirt, oxide scale, rust, and paint coatings, with any residual traces appearing only as minor discolorations or streaks.
Key Features and Components
1.Main Blast Cabinet:
Equipped with an inspection door for maintenance and monitoring.
2.Blast Wheel Units:
High-efficiency blast wheels propel abrasive media (e.g., steel shot) at high speed onto the rebar surface to remove rust and scale.
3.Abrasive Circulation System:
Includes a separator, bucket elevator, and screw conveyor to recycle and clean the abrasive media, reducing waste.
4.Dust Collection System:
Advanced cartridge filters capture and remove dust generated during the blasting process, ensuring environmental compliance.
5.Roller Conveyor System:
The machine features a roller conveyor system at both the inlet and outlet sides to transport the rebar through the blast chamber.
6.Control Panel:
Equipped with a PLC (Programmable Logic Controller) system for precise control over the blasting process.
Technical Parameters
1.Machine Dimensions: See the specific drawing provided by the manufacturer.
2.Shot Blasting Chamber:
Width: 1300 mm
Height: 500 mm.
3.Maximum Workpiece Size:
Length: 12000 mm
Diameter: 8-40 mm.
4.Maximum Workpiece Weight: 500 kg.
5.Surface Finish Level: Sa2.5.
6.Surface Roughness: 40-85 µm (dependent on abrasive size).
7.Noise Level: ≤95 dB.
8.Dust Content After Cleaning: 10 mg/m³.
Benefits
1. High Efficiency: The automated process ensures consistent and thorough cleaning of rebar surfaces.
2. Improved Surface Quality: Achieves a high-quality surface finish suitable for subsequent coating or welding.
3. Environmental Protection: The enclosed system and dust collection unit minimize environmental impact.
4. Customizable: The machine can be tailored to meet specific requirements, such as workpiece size and production capacity.
Applications
1. Construction: Cleaning and preparing rebar for use in reinforced concrete structures.
2. Steel Manufacturing: Surface treatment of steel rebar before coating or galvanizing.
3. Infrastructure Projects: Ensuring high-quality surface finish for durability and longevity.
