8474.90.00Ball Mill Liner Segments
High-chrome cast iron liner segments that line the interior of ball mills for grinding mineral ores into fine powder. These sacrificial parts protect the mill shell and enhance grinding efficiency in mineral processing operations.
8474.90.00Cone Crusher Mantle Bowls
Manganese steel bowl liners and mantles for cone crushers that provide secondary and tertiary crushing of mineral ores through compression. These precision-machined parts form the working surfaces of the crushing chamber.
8474.90.00Grinding Mill Trunnion Bearings
Large split spherical roller bearings supporting trunnion ends of SAG and ball mills for ore grinding. These precision parts enable rotation under heavy mineral loads, ensuring smooth operation of the grinding machinery.
8474.90.00Gyratory Crusher Mantle and Concave
Matched mantle and concave liners for gyratory crushers that process hard rock ores in primary crushing stages. Made from hard-faced alloys, these parts create the crushing chamber and are essential for ore reduction.
8474.90.00Impact Crusher Blow Bars
Replaceable manganese steel blow bars mounted in impact crushers to shatter aggregates and ores through high-velocity impacts. These wear parts are critical for the crushing action on solid mineral substances.
8474.90.00Jaw Crusher Wear Plates
High-manganese steel plates designed to line the jaws of primary jaw crushers used in mining operations for crushing ore. These parts are essential for protecting the crusher frame from abrasive mineral wear during grinding.
8474.90.00Mineral Jig Diaphragm Assemblies
Rubber diaphragm and frame assemblies that pulse water through ore pulp in mineral jigs for gravity separation of heavy minerals from gangue. These parts are essential for the operation of separating machinery.
8474.90.00Mixing Kneader Blades
Sigma or Z-blade rotors for batch kneaders mixing ceramic pastes, cement, or mineral powders into homogeneous masses. These profiled steel parts perform the kneading action in mineral processing machinery.
8474.90.00Rod Mill Shell Lifters
Profiled lifter bars bolted inside rod mill shells to lift grinding media and ore for cascading action during mineral grinding. These parts optimize charge motion in wet or dry mineral processing.
8474.90.00Sand Classifier Screw Conveyor
Helical screw conveyor blades and shafts for spiral classifiers that separate sand from fines in aggregate washing operations. These parts agitate and transport mineral slurries during classification.
8474.90.00Sand Mold Forming Rammer Heads
Interchangeable pneumatic rammer heads for compacting foundry sand into molds using machines for forming sand molds. Hardened steel or alloy construction withstands repetitive impacts in foundry operations.
8474.90.00Screw Classifier Tank Liners
Polyurethane or ceramic liners for rake or spiral classifier tanks that protect against abrasion during mineral classification and dewatering. These wear parts line the settling zones of the machinery.
8474.90.00Vibrating Screen Deck Panels
Polyurethane or rubber screen panels fitted into vibrating screens for separating aggregates and ores by size in mineral processing plants. These replaceable parts endure high abrasion from solid mineral flows during screening.
8474.90.00VSI Crusher Wear Tips
Tungsten carbide tipped wear blocks for Vertical Shaft Impact crushers that shape and crush aggregates through rock-on-rock impact. These high-wear parts are essential for fine mineral processing.
