Breakers 1 gravel mining, crushing with a pressing force generated when two broken face approach, the material broken. Jaw crusher, roll crusher, cone crusher is the main way to crush broken machinery 2, chipping is the use of force tines split wedge material to crushing crusher, the force of concentrated, adapted for crushing brittle materials 3, break the material broken face between two points as the bear concentrated loads (or fulcrum) beam hammer crusher, the material itself has broken off flexor surface. Motor-driven belt and pulley crusher, jaw by the eccentric shaft to move back and forth up and down, when the movable jaw to the fixed jaw plate movable pushing jaw crusher and efficient movement of the material being crushed or split pieces. When the action moving jaw and movable jaw plate in the eccentric shaft, spring back, the previously been crushed or split pieces of material from the lower jaw of the discharge port discharge. With the motor continuously rotating motor broken jaw for periodic crushing and waste material, to achieve mass production.
