Heavy-Duty Ball Mill Liners

Product Name: Cast Manganese & Cr-Mo Alloy Steel Wear Liners for Mineral Processing Ball Mills

Description:

Protect your milling assets and unlock maximum grinding efficiency with our ultra-heavy-duty Ball Mill Liners. Operating as the vital protective armor inside high-capacity grinding circuits, mill liners shield the main steel cylinder from devastating steel-on-steel impact while transferring the rotor’s rotational energy into the grinding media charge (steel balls).

We specialize in casting and precision-machining a comprehensive array of mill liner configurations, including Shell Liners, Head Liners, Feed Deflectors, and Grate Discharge Plates. Formulated via premium Chromium-Molybdenum Alloy Steel (Cr-Mo) and work-hardening Manganese Steel (Mn13Cr2 – Mn18Cr2), our liner profiles feature scientifically optimized wave and lifter bar geometries. Upgrading to our liners guarantees a perfect mill charge cascading trajectory, eliminating dangerous ball-on-liner direct impact, drastically slashing liner thinning rates, and minimizing structural mill vibration.

Customized Metallurgy for Diverse Milling Stages:

• Chromium-Molybdenum Alloy Steel (AS7228 / Cr-Mo): The premier choice for primary coarse grinding mills (SAG and large Ball Mills). It delivers an elite combination of high structural yield strength, zero cracking risks, and phenomenal wear resistance.

• Work-Hardening Manganese Steel (Mn18Cr2): Formulated for high-impact milling environments where oversized boulders or massive steel balls ($\ge \varnothing 100\text{ mm}$) are deployed. The surface work-hardens dynamically up to HBW 500+ while the core remains flexible.

• High-Chromium White Iron (Cr15 – Cr26): Optimized exclusively for secondary fine-grinding and regrind mill stages where slurry sliding abrasion is intense but severe impact is absent, delivering near-diamond wear life.

Key Technical Highlights:

• Optimized Lifter & Wave Profiles: Utilizing advanced CAD wear-simulation software, we tailor the height and face-angle of the lifter bars to match your mill’s specific RPM and ball charge size. This ensures perfect material lifting without dead-weight carryover.

• Precision-Machined Bolt Seating: All bolt holes and sealing grooves are CNC machined to tight tolerances. This creates a highly secure, flush fit against the shell that prevents dangerous slurry race-tracking (leaking behind the liner) and protects the shell from erosion.

• Guaranteed OEM Compatibility: Manufactured to strict drawings or OEM specifications, offering flawless drop-in replacements for major global ball mill brands, including Metso Outotec®, Sandvik®, FLSmidth®, CITIC®, and ThyssenKrupp®.
