Case Studies: Proven Mining Applications
FAQ: Common Questions from Mining Buyers
1）How long do rubber mill liners last?
Typically 1.5–4 times longer than steel liners, depending on ore type and operating conditions.
2）Can rubber handle highly abrasive slurry?
Yes. High-elasticity rubber absorbs impact and resists sliding abrasion effectively.
3）Is rubber suitable for corrosive environments?
Yes. Rubber provides excellent resistance to acids, alkalis, and slurry chemicals.
4）Can you replace existing steel liners?
Yes. Our solutions are designed for direct replacement or retrofit.
5）Do you provide installation support?
Yes. We offer remote or on-site technical guidance.
