Top Tips For Choosing The Right Abrasive Media For Your Project

Abrasive blasting is a finishing process, where a stream of abrasive material – also known as abrasive media – is propelled onto the surface of a workpiece. It serves various purposes, such as removing contaminants or previous coatings, altering the shape of an object, and smoothing or roughening a surface. There are various types of abrasive materials on the market, which is great in terms of finding something suitable for your project. However, knowing which is the best choice can be easier said than done. Here, the team at Surface Finishing Equipment Group (SFEG) explain a little more about the different abrasive options available, and offer a few useful hints on choosing the right material for the task at hand.

How To Mitigate The Risks When Shot Blasting

Shot blasting is one of the most crucial processes in manufacturing and finishing, but it can also be incredibly dangerous if not done properly.

The method of shot blasting involves propelling an abrasive media (i.e. a steel shot, glass beads or plastic grit) at a surface to polish it, remove excess contaminants or prepare it for a final covering.

Providing you’re equipped with the appropriate shot blasting equipment, the process is relatively straightforward. However, it comes with its own fair share of risks.

Let’s take a closer look at the hazards associated with abrasive blasting and what safety measure you can take to avoid them.

 

Potential health risks

Back when shot blasting was first developed, workers didn’t take many safety precautions. This meant they were at greater

How does shot blasting work?

Dirty, oxidised or unfinished materials are undesirable for all sorts of reasons.

For example, a material that is covered in scale, dirt and other debris isn’t easy on the eye, and oxidised materials can pose serious problems during the fabrication process (e.g. welding or machining).

Though you could apply a fresh coating to the surface without cleaning it, this is likely to cause a lack of adhesion. And any sharp burrs and edges could cause lacerations.

With that said, it’s always worth cleaning the material beforehand – whether it be a quick wipe down with a rag and suitable cleaning solution or shot blasting.

What is shot blasting?

Shot blasting and sandblasting are often used interchangeably. Though they belong to the same family of abrasive blasting processes, it’s important to note they

Top 5 Benefits Of Using Shot Blast Rooms

Want to add a smooth surface to a workpiece?

Shot blasting effectively removes rust, oxide, scale, and other remnants from surfaces so they can be restored or re-coated – providing an even texture.

Whilst several factors make shot blasting possible, a shot blast room is essential if you’re planning on making blast cleaning an in-house process.

As a leading supplier of complete finishing plants and systems, Surface Finishing Equipment Group (SFEG) knows everything there is to know about shot blast rooms.

Here we look at what they are and their effectivenes

What PPE Is Required For Shot Blasting?

Shot blasting is a popular technique used to remove debris and impurities from concrete, metal, and various other industrial surfaces.

Though the process itself is relatively straightforward – using a shot blasting machine to propel an abrasive at the surface at high speed – it’s crucial that all operators have access to the appropriate blasting personal protection equipment (PPE).

PPE will not only protect the user’s respiratory system, vision, and hearing but will also protect those working in the surrounding blast rooms and spray booths.

Here the UK’s leading suppliers of surface finishing equipment, Surface Finishing Equipment Group, share the best way to protect your workers when using abrasive media.

Top 6 Uses Of A Sandblasting Machine

 

Could your industry benefit from a sandblasting machine?

Sandblasting is the process of hurling abrasive media towards a surface at high speed to achieve a certain finish. There are two types used:

  • Reusable abrasive – the most economical option of the two and includes steel grit, aluminium oxide, glass bead and steel shot.
  • Expendable abrasive – typically used for open blasting where the blast media isn’t recovered or reused. Examples being iron silicate, garnet, olivine, stonegrit, and JBlast SC (a type of calcium silicate synthetic).

For many industry professionals, the sandblasting machine is an essential piece of equipment in the blast room – particularly for cleaning, deburring, and removing layers of paint and other coatings. There are various machines available and they all work differently. But for the most part, they propel media through a nozzle, via compressed air from an air

How Does An Air-Fed Mask Work?

Regular exposure to airborne toxic materials is a very real hazard in the finishing industry, whether you work in the paint shop, powder coating, or industrial spraying environment.

Harmful particulate can be easily inhaled into the lungs and have serious (sometimes fatal) consequences. Therefore, it’s crucial that you have the appropriate respiratory protection, including an air-fed mask.

 

What is an air-fed mask?

Simply put, an air-fed mask is a welding helmet with a built-in respirator.

It uses a battery-powered fan to provide clean air to the user and prevents contaminated particles from being passed through the filter. As a result, it provides maximum protection against dust, dirt, and other potentially harmful fragments.

Though air-fed masks are mostly used in the workplace, they’re also suitable for use at home – particularly by users who carry out welding tasks, or use materials that generate a lot
