The industrial waste processing line developed by Harden can transform industrial waste into high-quality high calorific value SRF/RDF, which can be used as fuel instead of fire coal, thus realizing the conversion of waste into energy. This processing line is mainly aimed at relatively pure waste leather, commercial waste plastics and other high calorific value solid waste, for more complex waste can be equipped with screen and density air sorting machine to complete the target to be processed. High torque double shearing shredder and special single shaft shredder for SRF/RDF will be used in the system. After secondary shredding, the material size can reach 30-80 mm (based on the requirement), and the standard-reaching rate is higher than 95%.
