Sustainable lime production and energy optimization

In the evolving context of sustainable lime production, energy optimization is not just a priority — it is a strategic imperative

In particular, combustion and cooling air supply systems in vertical lime kilns account for a significant portion of total energy consumption. Optimizing these systems plays a key role in improving both environmental performance and operational cost efficiency.

Within this framework, QualiCal has adopted the KAESER screw blower technology as a cutting-edge solution to reduce electrical consumption while enhancing performance. This initiative is fully aligned with the NEXT GENERATION LIME Vision 2025 — our commitment to driving the lime industry toward high-efficiency and low-carbon production.

Why KAESER Screw Blowers?

The KAESER screw blower with SIGMA profile is a smart, oil-free volumetric system specifically designed for continuous process applications like lime kilns. Compared to centrifugal or turbo blowers, it provides precise and stable air supply independent of system back pressure — a critical advantage in maintaining optimal kiln operation.

On Synthesis kilns, optimizing energy consumption enhances production efficiency with rapid ROI and long-term savings.

Energy savings of up to 25%, combined with long-term reliability, make the KAESER screw blower an ideal choice for kiln operators targeting operational excellence.

Key Advantages

• High-Efficiency SIGMA PROFILE: Offers wide-range control with low energy demand and high volumetric efficiency.
• Robust, Maintenance-Free Sealing: Sliding ring seals ensure long-lasting performance in dusty, high-temperature environments.
• Durability-Engineered Bearings: Four cylindrical roller bearings absorb all radial loads. Thermal separation of the oil chamber avoids overheating and removes the need for complex oil cooling systems.
• Integrated Sensor Network: Real-time oil level and temperature monitoring supports predictive maintenance and avoids unscheduled downtimes.
• SIGMA CONTROL 2: An intelligent control system offering pre-programmed modes and full process integration for enhanced monitoring, efficiency, and reliability.

Results and Impact

• 15–25% Electrical Consumption Reduction
• Noise Reduction for Safer Working Environment
• Lower Operational Expenditures (OPEX) — Lifetime Savings up to €4,000,000

Containerized and Modular Solutions — Fully Compliant with QualiSPACE

To further support flexibility and fast deployment, KAESER screw blowers can be integrated within custom fabricated enclosures and modified ISO containers under the QualiCal QualiSPACE modular infrastructure framework.

Whether expanding existing operations or launching greenfield installations, QualiSPACE solutions enhance operational safety, air quality, and lifecycle performance

With this integration, QualiCal reaffirms its mission: to deliver not only technological innovation but real value and sustainability to our customers’ operations. The KAESER screw blower is more than a component — it is a driver of performance in modern lime production.
