The independent intelligent control system of Harden QS four shaft shredder enables each cutter roll to have independent shearing and protection action, which improves the shear frequency and output. The main shaft of four shaft shredder is responsible for shearing, and the countershaft is responsible for feeding. By optimizing the shear structure and control principle, Harden four shaft shredder has achieved a major breakthrough in cutting efficiency.

In addition, QSH series four shaft shredder adopts hydraulic and motor coordinated drive, which not only has the effect of large torque and flexible control of hydraulic drive, but also retains the advantages of high efficiency of motor drive, energy saving,provides an excellent solution for heavy shearing conditions with high discharge size requirements.
