Abstract
The work presents the main results obtained at the application of the ultrasonic energy in the separating process of the rubber on the metallic insertions in the case of the transporting belts. Results refer mainly at the influence ultrasounds’ application has over the specific resistance at extraction of the metallic insertion from the rubber matrix, and these are quantified through an efficiency coefficient at extraction. The importance of the results presented in the work derives from the fact that the separating processes of the rubber on the metallic insertions are complex enough and big energy consumers, and the results presented in the work can be applied in practice and they allow a substantial increase of the economic profitability for the capitalization processes of the wastes of transporting belt reinforced with metallic insertion Keywords: belts, ultrasonic energy, rubber, metallic insertions
