In today’s highly competitive cement industry, manufacturers are under constant pressure to increase efficiency, lower energy costs, and boost production without compromising quality. For one mid-sized cement plant, the key to success came from making a strategic switch: replacing their traditional ball mills with vertical roller mills.
The results? A remarkable 20% increase in output, lower energy consumption, and improved material quality—all thanks to advanced grinding solutions offered by Cementl.
In this real-world case study, we’ll explore how the transformation unfolded and why vertical roller mills, especially coal vertical roller mills, are becoming the go-to solution for forward-thinking cement producers.
The Challenge: Stagnant Production and High Energy Costs
The plant in focus was operating in a highly competitive regional market. Despite running at near full capacity, it struggled with:
- Outdated grinding equipment
- Frequent maintenance breakdowns
- Inconsistent product quality
- High energy bills
Its traditional ball mill setup was no longer delivering the performance needed to stay competitive. The management team knew they had to invest in modern technology—but they also needed a solution that would offer fast ROI, lower operational costs, and scalability.
The Solution: Upgrading to Vertical Roller Mills
After evaluating several options, the plant chose to install a Vertical Roller Mill (VRM) system from Cementl. Known for their robust design and energy efficiency, Cementl’s vertical roller mills offered a reliable path toward modernization.
The plant installed two systems:
- A raw material vertical roller mill to replace the existing ball mill used for raw mix grinding
- A coal vertical roller mill for efficient, low-emission fuel preparation
Both systems were integrated with smart automation for real-time monitoring and control.
Why Vertical Roller Mills Made the Difference
So, what makes a vertical roller mill such a powerful upgrade?
1. Higher Grinding Efficiency
VRMs grind materials through pressure and shear between rotating rollers and a grinding table. This method is significantly more energy-efficient than the impact-based grinding in ball mills. Less energy consumption means lower electricity bills and reduced carbon emissions.
2. Compact, Integrated Design
Cementl’s VRMs integrate drying, grinding, and separating into one compact unit, which saves valuable plant space and reduces system complexity.
3. Optimized for Coal Grinding
Coal vertical roller mills are designed to grind and dry moist fuels in a single process. This makes them ideal for cement plants that rely on coal or petcoke as energy sources. With Cementl’s system, the plant improved fuel preparation consistency while cutting fuel usage by nearly 10%.
4. Consistent Product Quality
Automated controls ensure uniform particle size and stable kiln feed, leading to better clinker quality and fewer production interruptions.
The Results: 20% Output Boost and More
After implementing Cementl’s vertical roller mills, the cement plant saw significant improvements across the board:
| Metric | Before VRM Upgrade | After VRM Upgrade |
| Daily Cement Output | 2,000 tons | 2,400 tons |
| Energy Consumption per Ton | 110 kWh | 85 kWh |
| Coal Usage (per ton of clinker) | 130 kg | 117 kg |
| Downtime (monthly avg.) | 12 hours | 5 hours |
| Product Quality | Moderate | Consistently High |
That’s a 20% increase in cement output, a 23% drop in energy use, and significantly fewer maintenance shutdowns.
Cementl: Pioneering High-Performance Vertical Roller Mills
The success of this case is closely tied to Cementl’s commitment to innovation. Unlike off-the-shelf systems, Cementl’s vertical roller mills are custom-configured for each plant’s needs.
With smart diagnostics, predictive maintenance alerts, and AI-assisted process control, Cementl empowers cement plants to run smarter—not harder.
Their coal vertical roller mills come equipped with integrated classifiers and drying chambers, ensuring efficient fuel use even with varying coal moisture levels—a common challenge in many regions.
Long-Term Benefits Beyond the Numbers
Aside from production and energy savings, the plant also noticed:
- Improved environmental compliance with lower CO₂ and dust emissions
- Enhanced safety due to fewer moving parts and enclosed system design
- Higher team morale, as automation reduced manual workloads and stress
These outcomes helped the plant build a more sustainable, profitable operation—one that’s now better prepared for future industry challenges.
