Mill lifters & pulp lifters
ألواح رفع المطحنة و رافعات اللب
Control grinding-media motion and pulp discharge separately
Shell lifter bars and pulp lifters both perform a lifting function, but they are different components. Shell lifter bars control the lift and trajectory of grinding media. Inner and outer pulp lifters belong to the grate discharge system, carrying pulp from behind the grates to the discharge cone or trunnion.

Lifting grinding media and transferring pulp are different functions
Shell lifter bars withstand repeated impacts from grinding media and ore and transfer motion to the mill charge. Excessive or insufficient profile height and uneven wear can change media trajectories, liner loads, power consumption and throughput.
Pulp lifters sit behind the discharge grates to reduce pulp retention and maintain steady discharge. They must match grate openings, the discharge cone, trunnion, rotation direction and discharge-end structure. Shape alone is insufficient for reproduction.
Product pages
Find the component by mill and installation position
Individual product pages maintain confirmed OEM drawing references, part numbers, standard models and material records.
SAG and AG mill shell lifter bars
Alternate or combine with shell liners. Check lifting height, leading face, arrangement, and impacts from steel balls and large ore pieces.
SAG mill inner pulp lifters
Sit in the inner part of the discharge system and receive pulp passing through the grates. Check sectors, flow channels, rotation direction, grate openings and discharge-cone interfaces.
SAG mill outer pulp lifters
Connect the outer grate zone to downstream discharge channels. Check inner and outer ring positions, sector orientation, adjacent parts and the flow cross-section after wear.
Ball mill lifter bars and plates
Work with shell liners to lift steel balls and material. Check mill dimensions, liner arrangement, media size, speed and feed and discharge types.
Ball mill pulp lifters
Transfer pulp in grate-discharge ball mills. Check the grates, discharge sectors, centre cone, trunnion and required flow capacity.
Rod mill lifter bars
Provide controlled lifting of steel rods while avoiding abnormal rod tangling and local impact. Check wave or bar profiles, rod specifications, shell layout and end transitions.
Materials and structure
Control profile retention, impact cushioning and flow performance separately
Different positions may use metal, rubber or composite structures. Final selection follows drawings, operating conditions and the complete liner design.
Failure diagnosis
Use profile, fracture and discharge condition to identify the cause
Abnormal lifter wear often involves the liner profile, mill operation and adjacent liners together.
| Symptoms | الفحوصات ذات الأولوية | Impacts |
|---|---|---|
| Rapid wear of the leading face | Ore and media impacts, lifting angle, speed, layout, material and heat treatment | Changed media trajectories and fluctuations in throughput and power |
| Lifter bar fracture or breakage | Toughness, section geometry, casting defects, support, fastening, foreign objects and abnormal impact | Overloading of adjacent liners and risk of shell damage |
| Rubber tearing or loose metal inserts | Composite interfaces, sharp foreign objects, insert support, fastening and adjacent component heights | Loss of profile and foreign material entering the mill charge |
| Reduced discharge capacity | Blocked grate openings, lifter channels, rotation direction, slurry viscosity, pulp pool and discharge cone | Pulp retention and abnormal power consumption or throughput |
| Local erosion of pulp lifters | Channel bends, gaps, reversed installation, grate layout, materials and inner-to-outer ring transitions | Slurry leakage, uneven flow and shorter replacement intervals |
| Loose bolts or slurry leakage | Hole positions, contact faces, preload, washers, rubber settlement and reinspection procedures | Liner movement, hole damage and safety risks |
