What is the difference between shot blasting machine and sand blasting machine?

 The shot blasting machine is a kind of machinery-related machine, which is generally used to process the surface of the workpiece. Similar to it, there are the Sandblasting machine and the floor shot blaster. Here is the main difference between the shot blasting machine and the sandblasting machine.

There are many types of shot blasting equipment, such as through-type shot blasting machine, suspended shot blasting machine, crawler shot blasting machine, drum shot blasting machine, rotary table shot blasting machine, wire shot blasting machine, etc., shot blasting machine The principle of shot blasting is to make the motor start the impeller to make it rotate, and then the pellets are thrown to the workpiece, relying on the action of centrifugal force, through continuous collision and polishing, the workpiece is more beautiful and the life of the workpiece is improved.

 The floor shot blaster shoots the balls from a long distance to the surface of the workpiece. This kind of shooting process is shot blasting. Shot blasting to the parts containing residues to remove the shot blasting sand of the molding sand and core; shot blasting to the casting, forging, welding and heat treatment process parts to carry out the removal of skin, nodules, oxidized film, and rust The surface layer is removed.

Sandblasting Equipment

The sandblasting of the automatic sandblasting machine is a form of using air compression to quickly blow out the quartz sand to remove the surface of the part. It is also called sand blowing in the processing plant, which not only removes rust, but also removes oil, which is very effective for the coating process. The sandblasting machine is suitable for anti-rust treatment on the surface of the component; for the surface decoration of the component, in the steel frame structure, the use of high-strength bolts to carry out the connection is an excellent form, because the high-strength connection uses the sliding friction in the middle of the fusion surface to transmit force, Therefore, the quality of the fusion surface is very high. At this time, sandblasting must be used to solve the fusion surface. Sandblasting is divided into the dry sandblasting machine and wet sandblasting machines.

Both shot blasting and sand blasting machine can clean and decontaminate the workpiece. The purpose is to prepare for the next sequence, that is, to ensure the roughness requirements of the next process, and some are to achieve surface consistency. There is a strengthening effect, and the sand blasting machine is not obvious. Generally, shot blasting is small steel balls, and sand blasting is quartz sand. According to different requirements, the number of sub-items. Sandblasting and shot blasting are used in precision casting almost every day.
