The large-scale hydraulic driven primary shredder developed by Harden is strong, durable and with lower maintenance cost. It mainly targets at the size reduction of large material and the pre-shredding application of solid waste. With the help the multiple shredding mechanisms such as shredding, chopping, tearing and squeezing, it can easily accomplish the shredding task of mixed solid waste with complex components, including unsorted municipal solid waste, decoration waste and industrial waste.

Harden’s primary shredder can discharge the waste stream in relatively uniform size which is beneficial for sorting machine to separate or recycle material in the following process, so as to obtain recyclable material or high calorific refuse-derived fuel (RDF). Besides, the primary shredder can be redesigned as bag breaker through cutter replacement.
