Surface preparation plays a decisive role in the quality, durability, and performance of steel structures. Before painting, coating, or assembly, steel components must be properly cleaned to remove rust, scale, welding residue, and other surface contaminants. For manufacturers handling large volumes of steel plates, profiles, and structural parts, the Steel Structure Through-Type Shot Blasting Machine has become one of the most efficient and reliable solutions.

This article explains what a steel structure through-type shot blasting machine is, how it works, and why it is widely used across heavy industrial manufacturing.

What Is a Steel Structure Through-Type Shot Blasting Machine?

A Steel Structure Through-Type Shot Blasting Machine is a new type of specialized surface treatment equipment designed and manufactured according to actual production requirements. Unlike batch-type blasting machines, it is built for continuous operation, allowing steel workpieces to pass through the blasting chamber automatically.

The machine is mainly used for shot blasting cleaning of workpieces with different specifications and shapes, including steel structural components, plates, beams, pipes, and profiles. It integrates surface cleaning, stress relief, and surface conditioning into one continuous process, making it especially suitable for modern production lines.

Its core purpose is not only to clean steel surfaces but also to prepare them for subsequent coating or fabrication processes with consistent and repeatable quality.

Typical Applications in Industry

Because of its adaptability and productivity, the steel structure through-type shot blasting machine is widely used in industries where steel structures are a core material, such as:

• Machinery manufacturing

• Chemical equipment production

• Metallurgy and steel processing

• Construction and infrastructure components

• Heavy industrial fabrication

In these industries, workpieces often vary in size and shape, and production volumes are high. The through-type design ensures that cleaning efficiency keeps pace with manufacturing output.

How Does a Through-Type Shot Blasting Machine Work?

The working principle of a steel structure through-type shot blasting machine is straightforward but highly effective.

Steel workpieces are loaded onto a conveyor system, typically roller conveyors designed to support heavy loads. As the workpieces move forward at a controlled speed, they enter the blasting chamber.

Inside the chamber, multiple high-performance impellers project steel shots at high velocity toward the surface of the moving workpieces. These shots strike the surface uniformly from different angles, removing:

• Rust spots and rust layers

• Oxide scales formed during rolling or heat treatment

• Welding slag and spatter

• Other surface impurities

After blasting, the steel shots and debris are collected, separated, and recycled through the shot circulation system, ensuring efficient reuse of abrasive media. Dust and fine particles are extracted through an advanced dust removal system before the cleaned workpieces exit the machine.

Surface Results After Shot Blasting

Once processed, steel workpieces achieve a clean metal surface with controlled roughness, uniform luster, and consistent appearance. The cleaning effect meets the GB8923-88 Sa2.0–Sa2.5 standard, which is commonly required for steel structures before painting or coating.

This surface condition significantly improves coating adhesion, enhances anti-corrosion performance, and helps extend the service life of the finished product. At the same time, the blasting process contributes to the elimination of internal stress within the steel, which improves dimensional stability and reduces the risk of deformation.

Structural Design for Long-Term Operation

From a structural perspective, durability is essential for continuous industrial use. The Steel Structure Through-Type Shot Blasting Machine is built with high-wear-resistant components to ensure stable operation over long production cycles.

High-chromium steel guard plates are used in critical wear zones inside the blasting chamber, effectively resisting abrasion from high-speed steel shots. The impellers are made from Cr40 forged steel, offering strong impact resistance and consistent shot projection performance.

These design features reduce maintenance frequency and help keep the machine running reliably under demanding working conditions.

Energy Efficiency and Dust Control

Energy consumption and environmental performance are increasingly important factors in equipment selection. This machine is equipped with an intelligent frequency conversion system that adjusts motor speed according to actual operating load.

Compared with traditional fixed-speed equipment, this system can reduce energy consumption by more than 30%, improving overall operational efficiency without compromising cleaning quality.

Dust control is another key advantage. With a dust removal efficiency of up to 99.9%, the system effectively captures airborne particles generated during blasting. This helps maintain a cleaner workshop environment, protects operators, and supports compliance with industrial environmental standards.

Why Through-Type Design Improves Productivity

The through-type configuration is one of the main reasons this machine improves productivity. Continuous feeding and unloading eliminate repeated start-stop cycles associated with batch processing. Steel components move seamlessly from one production stage to the next, reducing waiting time and manual handling.

By lowering labor intensity and minimizing operator intervention, the machine allows manufacturers to focus on quality control and process optimization rather than repetitive cleaning tasks.
