Ball Mill Step Liner | High Manganese / High Chromium / Bimetallic Step Liner for Ball Mill

Ball Mill Step Liner We supply high‑quality ball mill step liners as critical shell wear‑resistant spare parts for cement and mineral‑processing ball mills. Unique stepped‑groove surface lifts steel balls efficiently, reinforces lifting performance and improves grinding capacity. Multiple material grades and custom sizes are available to meet various harsh grinding conditions, complying with global mining & cement industry standards.

Key Features & Advantages

• Various Material Options: High‑manganese steel(Mn13/Mn18Cr2), high‑chromium alloy, bimetallic composite, medium‑low chromium cast iron for different impact‑wear working conditions.
• Stepped‑Groove Structure: Special stepped‑groove surface obtains excellent lifting effect for steel balls, great for crushing large‑size feed inside coarse grinding chamber.
• Superior Impact‑Wear Performance: High‑manganese steel achieves impact work‑hardening; bimetallic composite combines tough substrate and high‑wear‑resistant working surface for longer service life.
• Wide Mill Compatibility: Fits φ2.2m, φ2.4m, φ3.0m, φ3.2m, φ3.5m, φ4.2m cement and ore‑processing ball mills.
• Flexible Order Support: Standard sizes in stock; non‑standard liners customizable per customer drawings or physical samples.
• MOQ: 1 piece for standard models; 10‑20 pieces for new custom‑made items requiring new casting moulds. Small trial orders negotiable for regular customers.
