The independent intelligent controlsystem of Harden Qs four shaft shredder enables each cutter roll to have independent shearing andprotection action, which improves the shear frequency and output. The main shaft of four shaft shredder is responsible for shearingand the countershaft is responsible for feeding. By optimizing the shear structure and control principle, Harden four shaft shredder hasachieved amaior breakthroughin cutting efficiency.

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