Four-combination mobile crushing station, the material is pre-selected by the feeder, crushed by the primary crushing and secondary crushing crusher, and then forms a closed-circuit system through the vibrating screen to realize the cyclic crushing of the material, which can effectively reduce the crushing process. Conveyor output for continuous crushing operation. The exchange system of different models of feeding unit, crushing unit and screening unit is realized on the same body, and the matching between the systems of the whole machine is suitable for a wider range of occasions and has a stronger crushing function.
