Elastic deformation absorbs particle impact, reduces noise and resists slurry wear. Applications include rubber and rubber-metal mill liners, elastomeric slurry pump wet ends, polyurethane screen panels and hydrocyclone liners. Rubber, PU and sealing elastomers require separate specifications.
Natural rubber, synthetic rubber, cast polyurethane and rubber-metal composites differ in chemistry, hardness, resilience, tear resistance, hydrolysis resistance and fluid compatibility. Match the material to particle size, impact angle, velocity, temperature, oils or reagents, and structural deformation.
These material options relate to mining equipment wear parts. Confirm each part's compound and construction from the equipment model, drawing and operating conditions.
Check mill diameter, speed, ball charge, maximum lump size, liner profile, fastening design and rubber-to-metal bonding.
For sharp coarse particles, high speeds, oily reagents or high temperatures, compare hard metal, synthetic rubber and specialized PU options.
Polyester and polyether PU, casting process, hardness and service medium differ. A quotation requires more than the description "polyurethane".
| Part / Position | Material and Construction Options | Main Properties | Specification Checks |
|---|---|---|---|
| Mill Shell Liners and Lifters | Wear-resistant rubber, rubber-metal composites or mixed liner systems for different positions. | Impact cushioning, noise reduction and low weight; metal inserts retain lifting profiles. | Mill model, speed, ball charge, lump size, profile, hole positions and installation/removal method. |
| Grates and Pulp Lifters | Rubber, rubber-metal composites or position-specific material combinations. | Slurry erosion and tear resistance, with control of aperture deformation and blockage. | Open area, slot width, flow, slurry concentration, minimum section thickness and fastening. |
| Slurry Pump Casing Liners, Side Liners and Throatbushes | Natural rubber, synthetic rubber, PU or mixed wet ends incorporating high-chromium white iron. | Particle impact absorption, erosion resistance and chemical compatibility. | Pump type, speed, particles, concentration, pH, oils or reagents, and temperature. |
| Polyurethane Screen Panel | Cast PU modules or metal-reinforced PU. | Fine-particle wear resistance, elastic anti-blinding action, aperture retention and dimensional stability. | Aperture, separation size, amplitude, temperature, wet or dry service, and reinforcement structure. |
| Hydrocyclone Liners / Spigots | PU, rubber, ceramic or zoned composite construction. | Resist high-velocity slurry erosion while maintaining bore and classification geometry. | Diameter, pressure, particle size, slurry concentration, bore wear and replacement interval. |
Finished elastomer properties depend on compounding, mixing or casting, vulcanization or curing, metal preparation and bonding. Shore hardness alone cannot establish performance.
Specify rubber or PU type, batch, fillers, fluid compatibility and temperature limits. Formulations may remain proprietary, but acceptance properties must be defined.
Control mixing, degassing, mould temperature, vulcanization and post-curing to prevent undercure, overcure, bubbles and localized property variation.
Check blast preparation, primer, insert location, rubber cover thickness and interface integrity. Assess debonding and fatigue risks in composite parts.
Inspect hardness, density, tensile and tear properties, resilience, abrasion, dimensions and appearance against the specification. Select compatibility tests for the actual slurry.
