Due to the larger size of the perforations, it is collected in a compartment 19 of the tank 30 corresponding to the second part 3 of the drum, a heavily loaded material and which requires complete reprocessing in suitable sorting devices or in sorting devices combined with a material dissolving device There also remains the possibility to pass the collected material through
