Sand Blasting Machines & Abrasive Blasting Equipment

Abrasive Blasting Industrial Surface treatment

Sandblasting, also known as abrasive or grit blasting, is a widely used surface preparation technique. In practice, the process uses a stream of abrasive material that strikes the surface at high speed. As a result, operators can clean, smooth or roughen a surface depending on the application. Industries commonly use abrasive blasting for cleaning surfaces, creating an anchor profile, deburring, desanding and achieving a specific surface finish. In addition, the process prepares the surface to ensure proper coating adhesion.

How does abrasive blasting work?

Abrasive blasting uses compressed air, water or a rotating wheel (turbine) to propel abrasive particles towards the surface. When these particles impact the surface, they actively remove contaminants such as rust, old paint and mill scale. At the same time, they create an anchor profile that allows coating systems to adhere properly. Furthermore, abrasive blasting can smooth surfaces, strengthen steel through peening, or carefully remove surface contaminants.

We offer several abrasive blasting methods, each designed for specific surfaces, working environments and production requirements. The main methods include compressed air blasting, open blasting, blast rooms, blast cabinets, vacuum recovery blasting and shot blasting with turbine-driven machines.

Compressed air blasting

Compressed air blasting cleans, smooths or shapes a surface by directing abrasive blast media through a stream of compressed air. This method typically requires a blast pot, blast hose, blast nozzle, compressor and appropriate protective clothing for the operator. As a result, it remains one of the most flexible and widely used blasting techniques. This method can be applied in different setups, depending on the working environment.

Shot blasting / wheel blasting

Shot blasting, also known as wheel blasting or turbine blasting, uses a rotating blast wheel to accelerate abrasive media onto the surface. Unlike compressed air blasting, this method does not rely on a blast nozzle or compressed air stream. Instead, the turbine creates a continuous and controlled flow of abrasive, making shot blasting highly efficient for repeatable surface preparation in industrial production environments.

Companies often use shot blasting machines for steel plates, profiles, pipes, castings, welded structures and automotive parts. The process removes rust, mill scale and contaminants while creating a consistent surface profile for coating or further processing. For high-volume applications, turbine blasting offers strong productivity, low operating costs and excellent process control.

Open blasting

When abrasive blasting takes place outdoors or on location, such as on ships, bridges, offshore platforms or other exposed structures, open blasting is often used. In these situations, environmental control becomes critical. Therefore, operators can use dustless blasting machines to limit environmental impact. These machines collect dust and recover the used abrasive for reuse. As a result, the process becomes more efficient and more cost-effective.

Personalised blasting rooms

In a personalised blast room, the system contains and collects dust within a controlled environment. At the same time, the blast media can be recycled. Consequently, companies reduce abrasive consumption and lower disposal costs for spent media.

Moreover, recyclable abrasives generate less dust, which improves visibility for the blaster. In addition, blast rooms allow full automation through robotic blasting systems. Especially when large surfaces require continuous blasting, automation delivers a short return on investment.

Cabinets made for blasting

When blasting smaller workpieces, operators typically use a blast cabinet. In this setup, the operator stands outside the cabinet and manipulates the blast nozzle through sealed gloves to process the parts inside. Airblast offers both pressure blast cabinets and vacuum injection blast cabinets. Furthermore, these cabinets can be fully automated. As a result, manufacturers can reduce labour costs when blasting large volumes of parts in a factory environment.

Blasting with Vacuum Recovery

Vacuum blasting combines traditional compressed air blasting with an integrated vacuum recovery system. This method cleans, strips and prepares surfaces while significantly reducing dust and debris.

Because the system automatically separates abrasive media from dust and loose particles, operators can reuse the media multiple times. Consequently, this reduces both abrasive consumption and disposal costs. Although vacuum blasting operates more slowly and offers less versatility than standard compressed air blasting, it eliminates airborne dust and enables abrasive reuse.

In addition, powerful machines such as the AB1070 can operate with cost-efficient steel grit. This further lowers abrasive consumption and supports efficient, controlled blasting operations.

Applications and industries

We supply blasting machines and equipment for companies that need reliable surface preparation in demanding industrial environments. Our solutions support both maintenance projects and production processes, from manual blasting on location to fully automated blasting systems in controlled facilities.

Common applications include pipeline coating preparation, steel structure maintenance, ship repair, offshore maintenance, bridge renovation, tank cleaning, foundry desanding, deburring of metal parts and preparation of surfaces before painting or coating. These applications are used across industries such as oil & gas, shipbuilding, steel construction, infrastructure, automotive, rail, foundries and general manufacturing.

By matching the right blasting method, abrasive and recovery system to each application, Airblast helps companies improve surface quality, reduce abrasive consumption and create a safer, more efficient blasting process.
