Steel Structure Shot Blasting Machine

Automatic Roller Conveyor Shot Blasting Machine for H Beams, Steel Profiles & Welded Structures Surface Preparation

Steel Structure Shot Blasting Machine is an automatic wheel blasting system designed for surface preparation of H beams, I beams, box beams, angle steel, channel steel, steel plates, pipes and welded structural steel components.

Using high-speed Steel Shot or Steel Grit propelled by centrifugal blast wheels, the machine removes rust, mill scale, welding slag, oxide layers and surface contamination while creating a controlled surface profile for subsequent painting, coating or corrosion protection.

Kholee Blast designs and manufactures customized steel structure shot blasting machines according to workpiece dimensions, production capacity, required surface cleanliness and workshop layout.

What Is a Steel Structure Shot Blasting Machine?

---

A steel structure shot blasting machine is an automated industrial surface preparation system used to clean and prepare structural steel by blast wheel before painting, coating, fabrication or delivery. 

The machine typically integrates:

In-feeding roller conveyor | Shot blasting chamber | High-efficiency blast wheels | Abrasive circulation and recovery system | Dust collection system | Out-feeding roller conveyor |Electrical control system

This configuration is particularly suitable for continuous production of H beams, I beams and other fabricated steel profiles.

How Does a Steel Structure Shot Blasting Machine Work?

The typical working process is:

Steel Structure → In-feed Conveyor → Shot Blasting Chamber → Abrasive Recovery → Separation → Dust Collection → Clean Steel Structure → Out-feed Conveyor → Painting / Coating

Steel Structure Shot Blasting Machine Applications

The machine can be configured for different structural steel products and production processes.

Typical applications: Steel Structure Fabrication | PEB Manufacturing | Bridge Construction | Shipbuilding | Heavy Machinery | Pressure Vessel | Oil & Gas Equipment | Steel Service Centers

Frequently Asked Questions

Q1: What is a steel structure shot blasting machine?

A1: A steel structure shot blasting machine is an automated wheel blasting system used to remove rust, mill scale, welding slag and surface contamination from structural steel such as H beams, I beams, profiles and welded components.

Q2: What steel structures can be shot blasted?

A2: Typical workpieces include H beams, I beams, angle steel, channel steel, box sections, steel plates, pipes and welded structural components.

Q3: Abrasive is used?

A3: Common blasting media include steel shot and steel grit. The correct abrasive size and hardness depend on the workpiece, required surface profile and blasting specification.

Q4: Can it achieve Sa 2.5?

A4: Yes. Properly designed and operated shot blasting systems can be configured to achieve Sa 2.5 surface cleanliness. The actual result depends on steel condition, abrasive type, blast-wheel configuration, conveyor speed and process parameters.
