Centrifugal blasting

Centrifugal blasting, also known as wheel blasting, is a process in surface preparation and cleaning technology that is used to remove dirt, rust, paint residue or other deposits from surfaces. This process is often used in industrial applications to prepare surfaces for further processing or to achieve a specific surface structure.

Centrifugal blasting is carried out using a blast wheel equipped with blast media such as steel shot, glass beads, aluminum oxide or other abrasive materials. The blast wheel is set in rotation, whereby the abrasives are propelled at high speed onto the surface to be treated. This controlled blasting process effectively removes deposits, old paint or rust and leaves a clean, prepared surface. The choice of abrasive depends on the type of surface to be treated and the desired results. Finer abrasives such as glass beads are often chosen for applications where a gentler surface treatment is required, while coarser abrasives such as steel shot are used for more robust cleaning requirements.

Centrifugal blasting offers several advantages, including efficient removal of contaminants, improved adhesion of coatings and the ability to control surface roughness. This process is used in a variety of industries, from metalworking and construction to ship and aircraft maintenance. However, it is important to take proper safety precautions when using shot blasting, as the process produces abrasive particles that can be potentially hazardous. The use of personal protective equipment and adherence to safety guidelines are therefore crucial to ensure the health of operators. Overall, shot blasting remains an effective method of surface treatment in various industrial contexts.
