Shot vs Sand Blasting
So you stumbled upon this site to learn the difference between shot blasting and sand blasting. The first thing you should become acquainted with is that they are both a form of Abrasive Blasting. In case you aren’t accustomed to the phrase we will inform you of what Abrasive Blasting exactly is.
Abrasive blasting is the process of effectively propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface, or remove surface contaminants. These breathtaking pieces of machinery are used for a variety of applications. They are used for blasting floors, wall, drums and anything else that needs resurfacing!
Abrasive blasting has several types of variations. The different types include bead blasting, sand blasting, sodablasting, and shot blasting. In this article we are going to take a look at shot and sand blasting and see the similarities and how they differ.
Shot Blasting Equipment for Concrete
All types of Blasting equipment use different media (abrasive material). The media ranges from minerals such as silica sand to metallic materials such as steel shot, steel grit and cut wire! Believe it or not even agricultural products such as crushed nut shells and fruit kernels are used in the blasting process for removing graffiti and also the removal of printed circuit board coatings.
Besides using portable shot blasting equipment the blasting procedures usually takes place in what is known as a Blast Cabinet. Essentially the blast cabinet is the place where the blasting takes place. It is the place where the material is blasted and crafted into the beautiful structure it was supposed to be. The operator stands outside of the cabinet viewing the object through a view. He then places his arms into the gloves and uses his foot to adjust the blast on and off. Even furthermore, the blast cabinet is contained in the blast room.
Sand Blaster vs Shot Blaster
So now you are wondering why I haven’t brought up the difference between a sand blaster and shot blaster? Well that is because there is none! The equipment is all the same! The only difference is the fact that sand blasting is using silica sand as its media, whereas with shot blasting they are using metallic shots that range from steel, copper to aluminum.
What has happened over the years is that they have upped the safety with abrasive blasting procedures. The National Institute for Occupational Safety and Health (NIOSH) approves what kind of safety equipment is required to provide the adequate levels of respiratory protection for blast operations. The large concern lately is the fact that sand tends to dissolve quickly which creates large quantities of dust. Because of that it exposes the operator to potential development of a debilitating lung disease called silicosis. Using it as an abrasive has been banned in Sweden, United Kingdom, Germany and Belgium for this exact reason.
Using different medias are useful for each project depending on what you are working on. Make sure you are with an experienced operator and are also using the right equipment!
