Working principle of jaw crusher spring

‌The spring of the jaw crusher mainly plays the role of reset and buffer. In the jaw crusher, the motor drives the eccentric shaft to rotate through the belt and pulley, so that the movable jaw periodically approaches and leaves the fixed jaw, thereby crushing the material in various ways such as squeezing and grinding. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, pushing the movable Jaw Plate to approach the Fixed Jaw Plate, and the material is crushed or split. When the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and the spring. At this time, the crushed material is discharged from the lower opening of the crushing chamber.

 

The role of the spring in the jaw crusher

‌ Reset function ‌: When the movable jaw descends, the spring provides sufficient elastic force to make the movable jaw plate leave the fixed jaw plate under the action of the pull rod to complete the discharge of the material.

‌ Buffering function ‌: The spring can absorb part of the impact force during the movement of the movable jaw, reduce mechanical vibration and noise, and extend the service life of the equipment.

Illustration and detailed description of the working principle of the spring

Since the specific working principle illustration and detailed description are not directly given in the search results provided, they can be understood through the following description:

 

‌Reset mechanism‌: When the movable jaw moves downward, the spring provides elastic force through the pull rod to make the movable jaw plate leave the fixed jaw plate and complete the discharge of the material.

‌Buffer mechanism‌: The spring can absorb part of the impact force, reduce mechanical vibration and noise, and protect the equipment.

Through these mechanisms, the spring plays a key role in the jaw crusher, ensuring the stable operation of the equipment and extending its service life.
