Movable jaw crusher jaw plate movement is the eccentric rod, and thrust with the board to achieve, It is by the flywheel, eccentric shaft, connecting rod, thrust plate and thrust board(known as cubits after board) composition. Two flywheels are mounted on both ends of the eccentric shaft. Eccentric shaft supported on bearings on the wall rack.
When the motor drive shaft rotation by pulley eccentric, connecting rods are up and down movement to lead the thrust campaign to make plate, before and after two thrust board by the formation of the Angle of the change to promote dynamic jaw movement. That can move around the jaw plate hanging a rotating shaft by swinging broken ore.. When moving the jaw forward swing, the horizontal rod through the spring to balance the jaw and thrust plate produced by the inertia force, so that moving the jaw and thrust plate closely, not separation.
When moving the jaw back, the spring can also play supportive role. Eccentric shaft crusher important parts, drive rod up and down movement. Because of its work under a lot of crushing force, generally of high quality alloy steel.
Link to withstand the tension as a result, it is manufactured with cast steel, in order to reduce the quality of connecting rod, connecting rod made often of the lower section of the special shapes. Large jaw crushing machine is mainly used a combination rod. Combination of link quality, small, save material, and has a simple device.
Thrust plate, also known as brackets, is passed to the jaw movement of a bar, and use it as a device. Change the length, you can also adjust the size of discharge mouth. Generally with the whole cast iron, cast whole also cast two pieces of, then bolts or rivets joined up.
