As a solid waste pretreatment equipment supplier for more than 10 years, Harden provides RDF preparation and pretreatment solutions for domestic waste. There are only three final products of the pretreatment line, which include high-quality alternative fuel (RDF / SRF) with a particle size of 98% less than 60 mm, an alternative fuel based on inorganic material, and recyclable metal. The whole process does not need manual participation and has good material compatibility for bulky waste or mattresses. Shredder and sorting machines as core equipment have stable working performance, which guarantees the low cost of RDF preparation.
