Complex pendulum jaw crusher works

Jaw crusher mobile jaw hanging on the mandrel can be used as side to side, when the eccentric shaft is rotated, the link down reciprocating motion to drive two thrust board also reciprocate, thus promoting the moving jaw do about reciprocating motion to achieve crushing and unloading . (Using double crank connecting rod mechanism), although the movable jaw larger force, crushing reaction force, but the eccentric shaft and connecting rod big discontinuity has, so much support mainframe, midrange machine industry for crushing hard materials .

Complex pendulum jaw crusher works

  Such crusher, the trajectory of each point on the moving jaw mandrel are in the center of the arc, arc radius equal to the distance from the axis point to the upper end of the lower end of the small arc arc large, low crushing efficiency, Since the crushing ratio of 3.6 trajectory so called simple: simple swing jaw crusher
Advantages: simple structure, less eccentric shafts and other transmission parts by force, since the moving jaw vertical displacement is small, the processing of the material is small excessive fragmentation is smaller movable jaw jaw plate wear
Complex swing jaw crusher
Moving jaw hanging in the upper end of the eccentric shaft directly, as the crank rod linkage, directly driven by the axis of the eccentric shaft, the lower end of the movable jaw hinge attached to the rear wall of the thrust plate support frame, when the eccentric shaft rotation when the movable jaw trajectory points by hanging circumference point (radius equal to the eccentricity) gradually becomes oval down, the downward bias the oval portion, the lower portion of the thrust plate until the connection point trajectory arc line Because of this machine moving jaw movement trajectory points is more complex, it is called complex swing jaw crusher.
