2 Working principle of jaw crusher

This series of jaw crusher song moving extrusion type, motor-driven belt and pulley , through the eccentric shaft to move up and down movement of the jaw , jaw rises when moving between toggle plate and moving jaw angle becomes larger, thus promoting the movable jaw close to the fixed jaw plate , while the material is squeezed, rubbing, grinding, such as multiple broken ; when moving jaw down, between toggle plate and moving jaw angle smaller, movable jaw plate under the action of leaving the rod, spring fixed jaw plate , and then the crushed material from the crushing chamber discharge port , with the mobile jaw crusher motor for continuous rotation of the crushing and nesting periodicity , to achieve mass production .
