Used shot blasting machine

Types of used shot blasting machine

The used shot blasting machine is a surface treatment method for many industrial parts. There are different types of this machine, such as used abrasive blast cabinets, used shot blast rooms, used blasting booths, and used tumbling blast machines.

• Used abrasive blast cabinets: The cabinet machine is small versus other shot blasting machines. People can put small parts inside the cabinet for blasting. The cabinet is safe for operators because the cabinet doors prevent stray projectiles from leaving the cabinet space. Once done, the operator can use gloves to take out the part. If the part needs further blasting, then the operator can put it back inside. The cabinet normally has a window so the operator can look at the blasting process.
• Used blast rooms: A shot blast room is larger and gives more space for blasting parts. Users can put in more giant objects for surface treatment with this room. It has a survival room lining to keep the walls and floor in good condition. The used blast room machine has special recovery and recycle systems for abrasive materials. These ensure the proper used material is extracted and processed.
• Used blasting booths: The booth works like the blast room but is not as large. It is like a customized box that protects the rest of the room from stray projectiles. A used blasting booth is better than the cabinet if the part is larger than what the cabinet can hold.
• Used tumbling blast machines: The tumbling machine is quite different from the previously mentioned ones. It uses a rubber belt to support and hold the workpiece. While the belt runs, the workpiece will be tumbled and blasted simultaneously. This machine is fit for barrel coating parts.

Q&A

Q: What is the process used in a shot blasting machine?

A: The shot blasting process involves four steps: loading, blasting, unloading, and recycling. First, the target parts are loaded onto the machine. Then, the impeller or turbine will start to rotate, shooting the blasting media onto the surface of the target part. After the blasting process is over, the target parts are unloaded from the machine. Then, the used blasting media will be collected and recycled through a conveyor belt system.

Q: What is the difference between shot blasting and shot peening?

A: Although shot blasting and shot peening are similar, they have different targets. The objective of a shot blasting machine is to clean, smooth, or polish the object by removing any slags or contaminations. On the other hand, the goal of shot peening is to improve the fatigue life of the target object by introducing compressive residual stresses in its surface layer.

Q: Can a Used shot blasting machine improve the metal's quality and increase sales?

A: Yes, using a used shot blasting machine can improve the quality of the metal by increasing its surface-level resistance.
