Complete Range of Ball Mill Spares

Beyond primary liner components, ball mills require numerous supporting parts that are critical to reliable, continuous operation. Trunnion liners protect the feed and discharge openings from abrasive wear, typically manufactured from chrome-moly steel or rubber depending on the trunnion configuration and ore properties. Feed chutes and spout liners direct incoming ore into the grinding chamber and are commonly fabricated from AR400 or AR500 abrasion-resistant plate, often with rubber or ceramic lining for extended service life. Discharge screens and classifiers—available in wedge wire, perforated plate, or polyurethane panel configurations with apertures from 1 mm to 25 mm—control product sizing downstream of overflow or grate discharge mills. ATF supplies the complete range of ball mill components, each manufactured to the dimensional tolerances and material specifications required for your specific mill installation.

Whether you need a single replacement trunnion liner, a set of high-strength liner bolts in Grade 10.9 or 12.9 per ISO 898-1, trunnion seal assemblies, or a complete mill reline package including all liners, lifters, grates, hardware, and consumables, ATF can source and manufacture every part matched to your specific mill configuration. Our engineering team works from OEM drawings, reverse-engineered measurements, or 3D laser scan data to produce components that fit correctly on first installation, minimising shutdown duration and eliminating costly rework. With manufacturing capacity supporting mills from 1.8 m to 7.9 m in diameter across all major OEM brands, ATF delivers a single-source solution for ball mill maintenance and capital spares inventory.
