Customer Background
A large mining company had its Raymond roller mill operating at low efficiency for a long time. The Raymond roller mill output remained more than 15% below the design standard, impacting overall production performance.
Challenges
The client had conducted self-inspections but could not identify the root cause. They faced low output and high energy consumption, urgently requiring professional diagnosis and a complete solution to restore production efficiency.
Our Solution
After an on-site inspection, our technical team quickly identified two key issues:
- Core part wear: Grinding rollers and grinding ring were severely worn, reducing grinding efficiency.
- Operational parameter imbalance: Material feeding was uneven, and the classifier speed was not set optimally.
We immediately implemented a targeted solution:
- Efficient replacement: High-performance wear-resistant grinding rollers and grinding ring were installed.
- Precise parameter adjustment: Key parameters, including feed rate and classifier speed, were reset together with the client’s operators.
Results and Benefits
- Significant output increase: The mill output not only recovered to the design standard quickly but also improved by 30%.
- Stable operation restored: Vibration and noise were reduced, ensuring smooth and reliable mill operation.
- Long-term trust established: Following this successful collaboration, the client established a long-term supply and maintenance partnership with our company.
Expert Insight
"Many output issues seem complex but are often caused by core part wear and parameter imbalance. Quick and precise actions are key to minimizing downtime losses." — Our on-site technical engineer
