Sandblasting refers to the process where sand and other materials get shot at a high speed through a machine onto the surface of a hard material until the surface is sanded smooth. It is mostly done when you wish to remove previous finish on the surface of rust or when you wish to prepare the surface for a fresh coat of paint. The materials used in the process will vary depending on how easy or difficult it is to remove the coating and the impact it can withstand.

When purchasing sandblasting equipment there are some factors that you must consider.
Type of the sandblaster

In this type sand is placed in a hooper, and then it is mounted on the sand blaster guns. Which are then connected to an air compressor. When you press the trigger, air comes from the nozzle and sand falls from the container and out through the nozzle at a high speed. Then there is the siphon blaster that works the same as the gravity fed blaster but the hooper is below the nozzle. Finally, there is the pressure sand blaster. It usually makes use of canisters of sand that are highly pressurized.
The appropriate size
Sandblasters come in different sizes. The smallest is the mini sand blaster that is handheld and portable. They were designed to specifically work on tight spaces and for detailed work. They usually have smaller sand blaster guns to handle delicate projects. Then there is the large sand blaster that is usually mounted in a cart with wheels for portability. Finally, there is the industrial sandblasters that are usually mounted on a truck. They are mostly used for large outside projects. They are mainly used by construction workers.
