Dry blasting is also known as grit blasting, sandblasting and abrasive blasting.
Sandblasting is the process of using compressed air to propel abrasive media at a surface to clean, (usually paint & rust),deburr, or to prepare a surface for a coating of some sort.
There are two kinds of sandblasters or blast cabinets: “Suction” / “Siphon”" & “Pressure” Blast Systems.
Pressure systems are ten times faster & much more effective, but also quite a bit more expensive.
There are two basic kinds of sand blasters: Blast Cabinets & Portable Blasters.
A typical blast cabinet consists of...
- Blast cabinet enclosure
- A good source for lighting the cabinet.
- Blast gun for directing the abrasive blast
- Compressed air to accelerate the slurry
- Exhaust system to maintain cabinet visibility
There is a wide variety of abrasive blast media out there each has its purpose.
Some of these include minerals ground to specific size for specific finish results as well as engineered products such as plastic media.
