1. Single-stage jaw crusher eliminates the congenital defect of "reduced force state" in the mechanical structure of traditional jaw crusher, and changes into "increased force effect", making the mechanical structure of jaw crusher more scientific and reasonable.
2. "Two-stage crushing with one machine" or even "Three-stage crushing with one machine" has been realized, which can directly crush large materials below 500mm into sand or powder below 5mm at one time, creating a precedent for jaw crusher to realize the function of "fine crushing" (sand making).
3. Using "coarse crushing" equipment to do "precision work" is convenient to use and maintain, reduces the technical requirements for on-site machine maintenance and operators, and is easy to hire or train.
4, greatly simplifying the crushing production line, saving investment (omitting the second and third crushers and conveyors), saving land, saving energy and reducing consumption, and facilitating management. It not only promotes the technological progress of "crusher", but also promotes the technological progress of "crushing production line".
