Centrifugal wheel

The centrifugal wheel principle is used in surface technology. The abrasive is accelerated to the required speed by a rapidly rotating paddle wheel. The fast and large-area processing of many components in a short time with little energy consumption is the most important advantage of this system.

The prerequisite for using this process are large, less complex components. It is not very suitable for complex components, as the distance between the blasting material and the blower wheel varies too much, which would result in very different levels of residual compressive stress . Only round abrasives can be used with this process, since angular abrasives cause the blades to wear out too quickly , but above all because the surface hardening effect is negated by fine cracks in the surface. The systems are usually so large that mobile use is impossible.
