Abstract
An efficient method of cleaning various workpieces is the so-called wet blasting, by which the workpieces are exposed to a spraying of water with a content of hard macro particles. Optimally, this blasting medium should be recirculated, but this implies noticeable problems with respect to separation of cleaned-off dirt and worn-down blasting particles. The invention provides for a system for processing units enabling these problems to be overcome in a relatively simple manner for achieving a high efficiency and low costs of the combined system.
