Hydrated Lime Moisture

Overview
Hydrated lime, also known as slaked lime, is produced through the controlled addition of water to quicklime (calcium oxide). This exothermic reaction produces calcium hydroxide, a soft, white, slightly water-soluble powder used across a range of industries, including construction, civil engineering, agriculture, chemical production, and water treatment.
Maintaining the correct moisture content throughout the hydration process is essential. Too little moisture results in incomplete hydration, while excessive water leads to clumping, poor flow, and handling difficulties. Moisture that exceeds acceptable limits can also increase shipping weight and render the material unusable in precision applications.
The MoistTech IR-3000 Near-Infrared (NIR) Moisture Sensor provides continuous, real-time monitoring to ensure optimal hydration and drying performance, improving both product quality and process efficiency.
Why Measure Moisture
Accurate, real-time moisture monitoring delivers multiple process and product benefits.
Quality Assurance
Energy Efficiency
Reduce Waste
Process Stability
RECOMMENDED MEASUREMENT LOCATIONS
Sensor 1 – Hydration Feed
Monitors the quicklime-to-water reaction mixture at typically 10–18% moisture to ensure proper hydration.
Sensor 2 – Post-Hydrator / Dryer
Measures moisture following initial hydration and drying at 1–3% to optimize dryer performance and prevent clumping.
Sensor 3 – Final Product / Storage
Verifies moisture before storage or packaging at ≤1% to ensure flowability and prevent excess weight.
Understand the Process
MoistTech’s flagship sensor is the IR-3000 and can be applied to many different applications. Depending on the product being manufactured, various on-line and off-line solutions are available for your moisture and coating measurement needs.
