What it is
High-calcium limestone formulated for controlled CaO delivery in cement raw mix systems, where Lime Saturation Factor precision governs clinker mineralogy, burnability, and kiln stability.
What it does
- Delivers controlled CaO input for accurate LSF correction
- Stabilises raw mix chemistry and clinker mineral formation
- Improves burnability and supports consistent thermal conditions
- Reduces corrective interventions and process deviations
Where it’s typically used
Cement plants where LSF correction, raw mix consistency, and clinker quality are process-critical requirements.

FAQs
If you have questions about limestone products, specifications, or typical applications, the answers below address some of the most common topics. For anything more specific, our technical team is happy to help.
Why is LS Booster the preferred choice for LSF-critical cement operations?
Its CaO ≥ 52% purity and tightly controlled impurity profile deliver exact Lime Saturation Factor correction — eliminating variability at the source before it reaches the kiln.
How does LS Booster support clinker consistency in high-silica raw mixes?
By counterbalancing excess silica with precision-grade calcium input, LS Booster stabilises raw mix chemistry — translating directly into predictable clinker quality and reduced process deviations.
What makes LS Booster operationally superior for kiln management?
Low MgO (≤ 2%) and SiO₂ (≤ 3%) in the Premium grade improve burnability and sustain stable thermal conditions — giving plant managers greater control with fewer corrective interventions.
