Fully automatic calcium hydroxide production line with precision water & temperature control. Engineered by CRONUS — a subsidiary of Guilin Mining Machinery with 50+ years of manufacturing heritage.
A Legacy of Excellence in Mineral Processing Equipment Since 1973
CRONUS is the international trading arm of Guilin Mining Machinery Co., Ltd., a premier Chinese manufacturer established in 1973. With over 50 years of equipment manufacturing history, our parent company is one of China's earliest and most respected mining machinery enterprises.
Headquartered in Guilin, Guangxi — a region known as the heart of China's calcium carbonate industry — our company has grown from a state-owned pioneer to a modern high-tech enterprise. Today, our lime hydration equipment serves customers across 30+ countries worldwide.
We specialize in complete calcium hydroxide (hydrated lime) production lines, integrating crushing, grinding, classification, hydration, and packaging systems — all engineered in-house for maximum compatibility and performance.
Understanding the science behind our advanced lime slaking technology
Quicklime (CaO) is precisely metered into the slaker through an automated feeding system. Particle size is optimized for maximum reaction efficiency.
The core exothermic reaction: CaO + H₂O → Ca(OH)₂ + Heat. Our system injects water at precisely controlled ratios through multi-stage spray nozzles, ensuring complete hydration with zero unreacted quicklime.
Advanced PID-controlled water injection maintains optimal reaction temperature (90-105°C). Real-time moisture sensors ensure the final product achieves target humidity (≤1% free moisture), preventing over-hydration or under-hydration.
Hydrated lime passes through an integrated classifier that separates fine Ca(OH)₂ powder from residual grit. The finished product is collected via a dust-free pneumatic conveying system, ready for packaging or silo storage.
Engineering excellence that sets us apart
Multi-stage intelligent water injection with PID control algorithm. Water-to-lime ratio dynamically adjusted in real time based on feed rate and quicklime reactivity — achieving ±0.5% accuracy.
Integrated temperature monitoring at multiple points throughout the hydration chamber. Automated cooling/warming ensures the exothermic reaction stays in the optimal 90-105°C range.
Siemens PLC with touch-screen HMI enables one-touch start/stop, recipe management, and full process visualization. Remote monitoring via industrial IoT.
Patented multi-blade stirring mechanism ensures thorough mixing. Achieves ≥99% hydration conversion rate, producing Ca(OH)₂ with purity exceeding 93% and fineness up to 325 mesh (45µm).
Fully enclosed design with integrated pulse-jet dust collection system. Emissions well below 20 mg/Nm³. Compliant with the strictest environmental regulations worldwide.
Critical wear components in 304/316L stainless steel or high-manganese alloy. Designed for 24/7 continuous operation — typical service life exceeds 10 years.

Hydrated lime (calcium hydroxide) serves diverse industries worldwide
Autoclaved aerated concrete (AAC), mortar, plaster, calcium silicate board, and soil stabilization. Hydrated lime improves workability, water retention, and durability.
Flue gas desulfurization (FGD), wastewater treatment, acid mine drainage neutralization, sludge stabilization, and drinking water softening.
Flux agent in steelmaking, sinter plant additive, and non-ferrous metal processing. Removes impurities like phosphorus and sulfur from molten metal.
Production of calcium stearate, calcium hypochlorite, bleaching powder, epoxides, and various organic intermediates.
Soil pH amendment, animal feed calcium supplement, sugar refining, corn tortilla processing (nixtamalization), and food-grade acidity regulator (E526).
Kraft pulp cooking, bleaching, and paper filler coating. A key component in the sulfate pulping process and paper recycling.
