By moving jaw to break the cyclical movement of materials in the movable jaw hanging around the center axis of the fixed jaw during the swing, in the jaw between the two materials will be crushed, split and bending combination effect. The beginning, less stressful, so reducing the size of the material, the material close to each other, squeeze tight; when the pressure rises above the material's strength can bear, that is where the breakage occurred. On the contrary, when the movable jaw to leave the fixed jaw swings in the opposite direction, downward movement of the material is by weight. movable jaw of each cyclical movement of materials by a crushing effect, to get some distance from the next row. after several cycles, the material begins to be broken machine discharge from the mouth outside with the continuous rotation of the motor for the periodic motion of mobile jaw crusher crushing and waste material, to achieve mass production.　 　

　 　1．Host structure design more reasonable，high-quality steel welding through CO2 protection ,durable； 
2．Eccentric shaft by alloy steel forging finishing, high bearing capacity;
3．Using high quality bearing, rare lubrication , improve useful time ,smooth operation , Maintenance convenient;
4．Deep cavity design , the speed and meshes angle are the optimized rational matching, ensure maximum yield;
5．Cubits board without lubrication, when the overload protection main engine, enhance the safety;
6．Hydraulic adjustment discharging port , easy operation and simple maintenance, improved productivity.
