# Roller Conveyor Shot Blasting Machine for PEB Structures

## Roller Conveyor Shot Blasting Machine for PEB Steel Structures a Efficient Surface Preparation

A **Roller Conveyor Shot Blasting Machine** is an advanced surface preparation system specifically designed for **Pre-Engineered Building (PEB) steel structures**. It efficiently transports heavy steel components such as **H-beams, I-beams, columns, channels, angles, plates, fabricated structures, and welded assemblies** through the shot blasting chamber at a precisely controlled speed. This ensures thorough cleaning, rust removal, mill scale removal, and surface profiling before painting, galvanizing, or further fabrication.

The automated roller conveyor system enables continuous operation with minimal manual handling, significantly improving productivity while delivering a uniform **SA 2.5 surface finish**. It is an ideal solution for PEB manufacturers, structural steel fabricators, bridge component manufacturers, and heavy engineering industries.

## Key Features

* Heavy-duty roller conveyor designed for handling large and heavy PEB steel sections.
* Variable speed drive for controlled movement through the blasting chamber.
* Uniform shot blasting for consistent surface cleaning and roughness.
* Continuous automated operation with high production capacity.
* Efficient removal of rust, mill scale, welding slag, and old coatings.
* Reduced manual handling and improved workplace safety.
* Robust construction with wear-resistant components for long service life.

## Main Components

* **Heavy-Duty Roller Conveyor:** Wear-resistant steel rollers designed to carry high-load structural members.
* **Drive System:** High-performance motor, gearbox, chain/sprocket, or shaft drive for synchronized conveyor movement.
