Method for efficiently preparing high specific surface area calcium hydroxide


High-surface-area calcium hydroxide is widely used in industries such as environmental protection, chemical engineering, and flue gas desulfurization. Our company provides complete production equipment solutions, integrating advanced process technologies, precise process control, and reliable automation systems to ensure stable product quality and high production efficiency
Production Process
Raw Material Preparation
High-purity limestone (CaCO₃) is used as the raw material to ensure product purity and stability.
Lime Calcination
Limestone is calcined in a rotary kiln or shaft kiln at temperatures of 900–1100°C to produce calcium oxide (CaO).
Digestion Reaction
Calcium oxide reacts with water in a high-efficiency digester to produce calcium hydroxide (Ca(OH)₂). A specialized digestion process achieves a high surface area.
Fine Classification
Airflow classifiers or precision screening equipment are used to achieve the desired particle size distribution.
Surface Treatment
Surface modification can be performed upon customer request to enhance product performance in specific applications.
Packaging
Moisture-proof, sealed packaging is used to ensure product quality during storage and transportation.
