Ball Mill Liners Case Study
Supporting Stable Grinding Production in Dakar Senegal
We recently supplied a full set of custom ball mill liners to a mining company near Dakar Port in Senegal for upgrading their wet ball mill.
The mining site operates a complete crushing and grinding production line:
2 sets of large jaw crushers
Impact crusher
HP300 cone crusher
Ball mill grinding
The plant processes high hardness granite and magnetite ore, which are highly abrasive and create heavy wear on liners.
After fine crushing by the HP300 cone crusher, the feed size entering the mill is controlled under 20 mm, ensuring stable and continuous grinding capacity.
Operational Challenges
Before using our liners, the mine faced several practical problems.
The original liners wore out quickly, especially at the lifter bars.
Uneven wear patterns led to frequent shutdowns and inspections.
The standard liner design could not lift steel balls efficiently.
This caused weak impact force and unstable grinding performance.
Frequent liner replacement and maintenance increased downtime
and gradually raised long term operating costs.
Customized Solution
To solve these issues, we developed a targeted solution
based on actual working conditions.
With long term experience in wear parts production,
we fully analyzed ore hardness, mill model, crushing process,
and on site operation habits.
For material selection, we used special wear resistant alloy steel.
This material provides excellent toughness to resist impact
while maintaining strong wear resistance under abrasive conditions.
For liner design, we optimized the height and angle of lifter bars.
This improves steel ball trajectory, increases impact force,
and ensures more stable and efficient grinding.
Production and Quality Control
During production, we strictly control every process step
from casting to final inspection.
Chemical composition is controlled to ensure stable performance.
Casting process is optimized to reduce internal defects.
Heat treatment is carefully managed
to balance hardness and toughness.
Machining and dimensional inspection ensure accurate fitting
and stable installation in the mill.
Performance Improvement
After installation, the mining plant achieved clear improvements.
Liner service life was significantly extended,
reducing shutdown frequency.
Grinding became more stable,
with more uniform product fineness.
Maintenance workload was reduced,
and overall operating costs decreased.
