Springs are the core elastic components of mining crushing equipment. The vast majority are heavy-duty compression springs, work in high-impact, high-vibration, and high-dust conditions. They mainly realize four functions: overload protection, reset, pre-tensioning, and shock absorption. They are widely used in spring cone crushers, jaw crushers, impact crushers, and others.
Functions of Springs in Different Machine Models
Jaw Crusher (Tie Rod Return Spring): Mounted at the rear of the return rod, this is a tension-compression spring.
When the pitman performs crushing and swings downwards, the spring is stretched.
When the eccentric shaft rotates, the pitman returns, and the spring pulls the toggle plate, resetting the moving jaw.
Spring Slack/Breakage: The moving jaw does not return to its original position, the toggle plate jumps, the equipment cannot discharge material, and severe abnormal noise is produced.
Spring Cone Crusher: Large compression springs encircle the frame, acting as an overload safety device.
Normal Crushing: The springs maintain pre-compression, keep the crusher chamber locked in place.
When uncrushable objects such as iron blocks fall in: Pressure surges, the springs are compressed, the support sleeve lifts upward, the foreign object is discharged.
After the foreign object is removed, the springs spring back to their original position, protecting the main shaft and liners from damage.
⚠️Distinguishing Hydraulic Cone Crusher: Spring cone crushers rely on springs for overload relief; hydraulic cone crushers rely on hydraulic cylinders, with the springs only assisting in pre-tensioning.
NP Series Impact Crusher: Overload Protection: When uncrushable hard objects such as iron blocks, rebar are mixed into the crushing chamber, they compress the impact plate & spring.
Constant Preload, Stable Output Particle Size: The spring provides a constant preload tension to the impact frame, firmly fixing the working position of the impact liner and ensuring a stable crushing gap between the impact plate and the rotor hammers.
Buffering and vibration reduction to reduce equipment wear: The high-speed impact of ore on the impact plate generates a huge impact force.

FAQ
1. What's the MOQ for Cutomized Spring?
MOQ 1pc. You can provide height, wider diameter, cicles, outer diameter, inner diameter. Or you can send the sample to us.
2. Can I customized my logo?
Yes, we provide laser printing.
3. Will colored coating affect the buffer and overload protection function of the crusher spring?
No. The paint is only a surface anti-corrosion layer, which does not change the internal metal structure, elasticity and compression performance.
