What is the best compression range?

The optimal compression rate is 15%-25% of free height to ensure the best damping effect.

Do you provide batch matching service?

Yes. We can support full set matching and customized solution service for different vibrating screen models.

Key features

High Strength Structure. The spring delivers firm support under heavy screening load. It keeps stable deformation during continuous coal washing.

Coal Washing Suitability. Rubber material resists coal slurry and alkali erosion. It works reliably in wet coal preparation plants.

Strong Buffer Function. It absorbs violent impact during high frequency screening. It protects screen mesh and main frame from stress damage.

Excellent Slurry Resistance. Optimized formula blocks moisture penetration into material. It avoids elastic performance decline in wet working sites.

Long Fatigue Life. The material endures millions of vibration cycles. It reduces spring replacement frequency for coal processing plants.

Stable Support Performance. Consistent elasticity keeps screen box level during running. It maintains accurate screening and grading result.

Easy On Site Replacement. Standard mounting dimension simplifies installation work. It shortens equipment maintenance downtime.

Good Resistance To Alkali. The compound withstands corrosive washing water condition. It prolongs the useful life of screen support parts.

Bulk Order Friendly. We support large quantity production and fast shipment. It secures stable supply for industrial screening lines.

Complete Quality Check. Every spring passes load and aging test before delivery. We provide reliable product for overseas coal mining buyers.

Product Q&A

Q:What is the advantage of rubber spring compared with steel spring?

Rubber springs support multi-directional shock absorption with lower noise and shorter resonance time, ideal for low-noise and stable operation scenarios.

Q:Is your rubber spring resistant to wet mine slurry?

Yes. Upgraded rubber formula resists slurry corrosion and aging, suitable for long-term use in coal washing and wet screening environments.

Q:Can you adjust the hardness of rubber springs?

We can customize different Shore hardness according to customer load requirements to match different vibrating screens.

Q:What is the service life of rubber springs?

Normally 0.5-2 years depending on working conditions, with better durability than ordinary market products.

Q:Will the rubber spring deform easily?

It features stable elastic recovery and uniform stress, not easy to permanent deform under standard compression range.
