The main work of the locking system is to make buttress locked between serrated lock sleeve and threaded sleeve in order to keep adjustment sleeve not being rotated in crushing operation and to keep the discharging port unchanged.
When we need to adjust the discharging port, locking cylinder is filled with hydraulic oil by hydraulic fluid, and the butterfly springs in locking cylinder is wholly compressed and unable to provide the locking force when hydraulic pressure reaches 150mpa, and at this right minute, the size of discharging port can be adjusted.
