A cleaning procedure relates to cleaning of clogged holes or passages of lesser diameter, such as deep through-holes or through-holes with light of varying sizes, in particular such holes in dies for through-pressing of materials at the manufacturing of pellets, as in particular dies employed at pelletizing of feedstuff pellets. By means of the procedure a comparatively fast cleaning is obtainable without any particular damaging of the material of the walls of the holes. A control procedure for a fast-operating cleaning means is described. As fast-operating cleaning means a fast-emitted, possibly with supersonic speed emitted, thin water jet is applicable. An apparatus to be used together with the procedure is described. By means hereof it is possible to clean radially oriented holes or passages in a die (1) for pelletizing by means of a water jet emitted from a nozzle (2A) under a very high pressure. |
