Getting To Know The Shot Blasting Machine: Common FAQs

Shot blasting machines are designed for some of the toughest surface debridement applications. These heavy-duty machines can transform a finished surface into a blank slate in a short amount of time. Here are a few things you may want to know.

What types of blasting medium can be used in a shot blasting machine?

Just like sandblasters, you can use a range of different types of blasting mediums in a shot blasting machine, but not like a sandblasting machine, you can use much larger mediums. Some examples of blasting mediums that can be an option with a shot blaster include:

  • Copper pellets 
  • Aluminum beads 
  • Organic mediums like cracked corn or corn kernels 
  • Steel grit 
  • Glass or ceramic marbles 

The type of medium used will depend on the application. Larger shot material is most often used for heavy-duty projects like removing powder-coated finishes from a piece of heavy equipment. 

How is shot blasting different from sandblasting? 

The primary difference between shot blasting and sandblasting lies in the medium used. Shot blasting, as already noted, involves using heavier mediums like pellets or larger particles, while sandblasting usually involves using some type of natural or synthetic sand. One other difference is the applications for which each type of equipment may be used. Shot blasting machines are more often used on larger or heavier pieces that can have denser, harder to tackle finishes. You are much more likely to find a sandblaster somewhere like a small machine or woodshop. 

What features should you look for in a good shot blasting machine for sale?

Shot blasting machines can be a major investment for your operation. Therefore, it is important that you know what features to look for in the best model before you head out to buy what you need. Many models exist from numerous manufacturers and they can all have unique attributes and features. Some of the most important features to look for include:

  • Dust-free operation capabilities 
  • Targeted operation to allow for little waste 
  • As few moving parts as possible to keep maintenance easy 

It is worth also noting that some shot blasters are specifically designed for use on surfaces and are mobile. If you are buying a rolling shot blaster for floor surface or road surface treatment, make sure you are getting a unit that is well-designed for portability. For example, the unit should be lightweight and easy to maneuver with nice wheels and a sturdy frame.
