Jaw Crusher has the structure of the main frame, eccentric shaft, the pulley, flywheel, moving E, side retaining plate, toggle plate, toggle plate rear screw transfer gap, reset spring, fixed plate and Events E-E group, etc. into which bracket also played the role of insurance. This series of jaw crusher broken for Qu Dynamic extrusion type, motor-driven belt and pulley, through the eccentric shaft so that moving up and down E-Sports, when the dynamic rise toggle plate and moving large angle between E, thereby promoting actin E board to set board close to E, at the same time material was extruded, molded, milled multiple broken; when moving down link, the toggle plate and moving smaller angle between E, E-board in the bar moving, springs from the role of E-board is scheduled at this time has been broken material from the mouth from under the crushing chamber, as the motor for rotating motor broken for cyclicalcrushing and nesting, to achieve mass production.
