Engineered Solutions for Wear, Flow, and Long-Term Performance
Polycorp delivers mining and milling components that stand up to the harshest processing environments. Our elastomeric liners, pulp lifters, and discharge systems are engineered to reduce downtime, increase throughput, and extend equipment life. With decades of experience in abrasion- and impact-resistant materials, Polycorp solutions are proven in mills and mineral processing operations around the world.
Engineered Protection for SAG, Ball, and Rod Mills
Polycorp designs and manufactures mill liners for every major mill type, using rubber and composite technologies to optimize wear life and performance. Our PolyStl™ and PolyKombo™ liners combine the strength of steel with the resilience of rubber, providing impact absorption, noise reduction, and faster relines. These liners are engineered for long-term reliability in high-capacity operations.
Optimized Flow for Maximum Efficiency
Our elastomeric pulp lifters improve slurry discharge systems, reduce slurry pooling, and improve slurry flow. Tailored to each mill’s geometry, they help balance wear patterns, minimize carryover, and enhance overall mill performance.
Durable, High-Performance Flow Discharge
Polycorp’s discharge systems and grate components are designed to endure the extreme abrasion and impact typical of mineral processing operations. Available in rubber and composite designs, they improve material discharge consistency and extend maintenance intervals.
Continuous, Reliable Material Handling
From trommels to grate plates, Polycorp’s grates withstand heavy abrasion while maintaining high open-area ratios for efficient classification. These systems improve uptime and deliver dependable performance in continuous-use environments.
