The QS four shaft shredder by Harden features an independent intelligent control system, allowing each cutter shaft to operate with independent shredding and protection actions. This design significantly boosts cutting efficiency and throughput. Unlike ordinary four shaft shredders where the main shaft handles shredding and the second shaft is for feeding, Harden's four shaft shredder achieves a major advancement in shredding efficiency through optimized shredding structure and control principles.

Moreover, the QSH series four shaft shredders utilize a cooperation drive mode with both hydraulic and motor drives. This setup enables high torque output and flexible regulation with hydraulic drive, while also maintaining the advantages of high driving efficiency and energy savings with mechanical motor drive. This disposal solution provides the ability to meet the requirement of small particle size discharge.
