Detailed explanation of the complete shot blasting process of the shot blasting machine

Shot blasting machine is a device that uses the high-speed impact force of shot blasting materials to clean and surface treat workpieces. Its working principle mainly includes the following steps:

1. Shot blasting material input: Firstly, the shot blasting material is input into the shot blasting chamber of the shot blasting machine, usually through the feeding port on the upper part of the shot blasting machine. Shot blasting materials can be steel shot, steel sand, aluminum shot, etc. Choose the appropriate shot blasting material according to the material and requirements of the workpiece.

2. Rotation of shot blasting chamber: Once the shot blasting material is put in, the shot blasting chamber will start rotating. There is a shot blasting machine in the shot blasting room, which is driven by a motor to rotate and achieve uniform distribution of shot blasting materials.

3. Shot blasting material spraying: After the shot blasting chamber rotates, the shot blasting material will be sprayed out by the shot blasting wheel. The shot blasting material sprayed out can effectively clean the oxide scale, rust, and dirt on the surface of the workpiece under the high-speed impact force.

4. Recycling of shot blasting materials: The cleaned workpiece and shot blasting materials fall into the bottom of the shot blasting chamber together. At this time, there is a recycling system in the shot blasting room that separates the shot blasting material from the workpiece through a vibrating screen. The shot blasting material is recycled and reused, while the workpiece continues to be transported downwards.

5. Re-enter shot blasting: After the workpiece continues to be transported downwards, it will be re-entered into the shot blasting chamber for shot blasting treatment. Repeat this process until the workpiece reaches the desired cleanliness and surface quality.

Shot blasting machines are widely used in various industries, mainly for surface cleaning, rust removal, descaling, deburring, increasing surface roughness, etc. Specific application areas include:

1. Steel structure manufacturing: Shot blasting machines can clean and rust the surface of steel structures, improve coating adhesion, and extend service life.

2. Automotive manufacturing: Shot blasting machines can clean the oxide scale and rust on automotive components, improve surface quality, and reduce defects.

3. Casting industry: Shot blasting machines can remove gravel and oxide scale on the surface of castings, improving the quality and appearance of castings.

4. Ship repair: Shot blasting machines can clean rust and seaweed on the surface of the ship, reduce resistance, and improve the speed and fuel efficiency of the ship.

5. Aircraft manufacturing: Shot blasting machines can clean the oxide scale and rust of aircraft components, improve surface quality and assembly accuracy.
