Surface preparation is an important phase in many sectors such as construction and manufacturing. Shot Blasting is quite advantageous and it is required for many surface preparation scenarios. Today, in this blog post, we will share tips for selecting a shot blasting machine for surface preparation needs.
What is a Shot Blasting Machine?
They are used for surface preparation needs in different sectors. Surface preparation means removing unwanted impurities from the surface and making it smooth. Shot blasting machines use abrasive materials to prepare the surface.
One of the reasons why many users may have struggled with Shot Blasting in the past is a lack of instruction on how to utilize it successfully. Understanding the fundamentals of shot blasting, such as the type of shot to use and the proper volume and combination, is critical for removing epoxy, glue, or paint and achieving the desired surface finish. Once you understand these fundamental ideas, you will realize how useful shot blasting is.
When we say “shot,” we mean the little steel balls that go on the blast wheel of a Shot Blasting machine. For those who don’t know, the Blast Wheel is the portion of the machine that throws the shot onto the area being blasted.
There are ten various shot sizes to pick from, depending on the sort of profile or texture you want to give the concrete, or whether you’re removing glue, epoxy, or paint. The most popular sizes, and the ones we recommend utilizing with our machines, are S330 to S780.
For glue or epoxy, use a tiny to medium-sized shot, or combine the two. Using too much shot can cause the glue to break up into large pieces and perhaps jam the machine.
For Paint, use a medium to medium-big size, usually a combination of sizes to achieve the desired profile.
Shot blasting equipment may be used to blast a variety of metal and steel items, including:
- Tumblast Shot Blasting Machine (Vibratory Belt Motion)
- Table Type blasting machine
- Hanger Type shot blasting machine
- Stone Shot Blasting Machine
- RBM (Rotary Barrel Type)
- Paver Block Shot Blasting Machine
The type of metal or steel item to be blasted, as well as its shape, design, weight, and size, determine the type of shot-blasting equipment required.
Tips to Pick the Right Shot Blasting Machine
Size of the Workpiece
You can pick the size of your blasting machine according to your requirements. So, determine the size of your workpiece and then choose the blasting equipment. Large workpieces such as tanks and pipelines need large-capacity machines. Hanger-type, wheel-blast, and table type blasting machines have large capacities and big chambers.
On the other hand, small to medium workpieces need small-capacity machines such as air-blast and tumblast shot blasting machines.
Type of Material to be Cleaned
Another tip is to consider the type of material you want to clean. Different surfaces and materials need different abrasive media and blasting techniques. For example, hard metal surfaces need steel shots and steel grits.
Operating Cost
Make sure to consider the cost of operating the shot blasting equipment and the abrasive media. Some machines need high maintenance and have high operating costs that can affect your pocket. So, consider the maintenance and repair cost of the machine before you buy it.
Conclusion
You can choose the right shot blasting machine for your surface preparation needs with the help of the above tips. Consider the machine type, abrasive media, workpiece shape and size, surface finish, and maintenance cost. Choose the right machine and get the best surface preparation results.
