1、With the adoption of world manufacturing crafts and high top manufacturing materials . 2、More advanced flexible jaw assembly make itself features long wearing capability Flexible jaw assembly adopt quality cast steel and driven by two large cast-steel fly wheel .And otherwise , the heavy eccentric shaft also adopt the forging mould processing ,which have made the JC series jaw crusher with higher reliability . 3、whole cast-steel structure can ensure the combination with the crushing frame and have greatly enhanced the ram strength while the non-whole bearing seat do not have this feature. 4、With the adoption of the finite element analysis ,the crusher have higher strength. 5、The crushing cavity adopt the symmetric structure of "V",which make the consistence between the practical feeding materials and the theory feeding width . 6、Discharge opening adjustment become more convenient .With the installation of wedge block discharge opening equipment, the JC series jaw crusher features more convenient , safety adjustment .
7、Larger bear specification and higher bearing capability .All of the JC series jaw crusher can installed the eccentric shaft bear with bigger and more durability compared with the same specification .And the high bearing capability and efficient labyrinth seal have greatly extended its service life . 8、With the adoption of the gear guard board and the efficient length of the jaw plate have ensured the high production .Railway construction features large investment cost and application ,long period ,which can efficiently promote the sand stone aggregate production equipment .And the railway high-speed construction have provided higher requirements for the sandstone aggregates particles and grades ,particular to the needle ratio of the basalt (diabase) gravel.
While the previous processing crafts of the cone crusher and impact crusher can't satisfy the present production requirement and SBM have developed some following products such as PFW impact crusher ,CS cone crusher , VSI5X sand-making machine ,portable mobile crushing plant ,which have greatly made up the market loss and promote the railway high-speed construction .Founded in 1995 and located in the beautiful Pudong New District ,Shanghai Shibang Machinery Co., Ltd. boasts a production base with more than 90,000 square meters and major in the research ,manufacture and sale to the mining crushing ,sand-making and industrial equipment ,which have provided high-grade sand-stone materials solution and complete equipment in the field of Highway, railway, water and other large projects.
For 15 years'research and development ,SBM are faced with the market with the professional ,seriousness ,honest, and pragmatic attitude .With the rich technical accumulation and new and high technology ,SBM have continuously improved the technical performance and reliability ,which have reduced the operation cost and reach the win-win strategy .
