Jaw crusher is the most widely used primary crushing products, according to its structural characteristics can be divided into simple pendulum and pendulum two. Today, I will lead you to know these two types of jaw crusher.
Simple pendulum jaw crusher
Crushing principle: the movable jaw is suspended on the shaft, which can be swung left and right. When the eccentric shaft is rotated, the connecting rod does the up and down reciprocating movement, and the two thrust plates also do the reciprocating movement, so as to push the movable jaw to do the left and right reciprocating movement to achieve crushing and unloading. This moving jaw is a kind of left and right reciprocating movement, the trajectory of each point on the moving jaw is a circular arc line centered on the suspension shaft, the movement trajectory is simple, so it is called simple pendulum jaw crusher.
Tilting jaw crusher
Crushing principle: the motor rotates the eccentric shaft through the belt and pulley, and the movable jaw plate moves periodically around the eccentric shaft to the fixed jaw plate, sometimes close to and sometimes away. When the movable jaw plate is close to the fixed jaw plate, the ore between the two jaw plates is crushed by extrusion, bending and splitting. When the moving jaw plate leaves the fixed jaw plate, the crushed ore is discharged through the discharge port of the crusher under the action of gravity. The moving jaw is directly suspended on the eccentric axis, and when the eccentric axis is rotated counterclockwise, it directly drives the moving jaw plate to make a complex swing. The motion trajectory of the moving jaw from top to bottom: at the top of the crushing chamber, the motion trajectory is elliptical; In the middle of the crushing chamber, the motion path is a flatter oval; At the bottom of the crushing chamber, the motion trajectory is almost reciprocating. Because the motion trajectory of each point on the moving jaw is more complex, it is called complex swinging jaw crusher.
Although the two types of structure are different, but their working principle is basically similar, only the movement of the jaw trajectory is different.
Tilting jaw crusher is generally made of small and medium-sized, because it in the crushing process, the moving jaw is subjected to huge extrusion pressure, and most of the action on the eccentric shaft and bearing above, resulting in the deterioration of the eccentric shaft and bearing force, easy to damage. However, with the emergence of large impact bearing, compound pendulum jaw crusher gradually to large-scale.
