The jaw plate of 600 jaw crusher is divided into fixed jaw plate and movable jaw plate

The jaw plate of the jaw crusher is divided into fixed jaw plate and movable jaw plate, which are wear-resistant parts of the jaw crusher. When the jaw crusher is in operation, the movable jaw is attached to the movable jaw plate and performs a compound pendulum motion, forming an angle with the fixed jaw plate to squeeze the stone. Therefore, the jaw plate is the most easily damaged accessory in the jaw crusher. During the circular motion of the jaw crusher when the eccentric shaft rotates once, the trajectories of the movable jaw at the top, middle and lower crushing points of the crushing cavity are completely different. At the top of the crushing chamber, the movement trajectory is elliptical, indicating extrusion, that is, large pieces of ore have entered the crushing chamber and begin to be crushed. In the middle of the crushing chamber, the motion trajectory is a flatter ellipse, indicating that the extrusion stroke is getting larger and the broken chunks are further broken. At the bottom of the crushing cavity, the motion trajectory almost changes from elliptical motion to reciprocating motion, indicating that the crushing stroke at the bottom is the largest. In this movement process, the first half of the elliptical extrusion movement can cause the large ore blocks to be crushed as soon as they enter the crusher. The second half of the elliptical push-down movement causes the ore blocks to continuously push downward and be further crushed until until leaving the bottom of the crushing chamber. This downward rubbing movement avoids the phenomenon of large pieces bridging, which is conducive to a smoother crushing process.
