Shot Blasting

Rotor & Seperator

Unlike air blasting, shot blasting does not use compressed air as the power for injecting abrasive media. The shot blasting uses motor rotation to rotate blades at a high speed. Abrasive media are forcibly fed to the blades and injected at high speed by the blade rotation.
The injection unit is normally called a "rotor" (sometimes called an impeller). There is a big difference between shot and air blasting. Shot blasting injects a far larger amount of abrasive media with less power. A comparison of the injection processes between one nozzle with a three-horsepower compressor and one rotor with a three-horsepower motor shows that shot blasting injects abrasive media 50 to 100 times that of air blasting per minute. (The value will vary depending on condition.) power.

For the mechanism, a shot blasting machine generally includes devices such as a bucket elevator and a screw conveyor to forcibly circulate larger abrasive media. (If the weight of your abrasive media is heavy, the media cannot be transferred by the suction force of a dust collector unlike air blasting.)
