Calcium hydroxide production line
A calcium hydroxide production line, also known as a slaked lime production line, processes quicklime through advanced processes such as grinding, hydration, and classification. The quicklime undergoes a chemical reaction to produce slaked lime.
Daswell powder tech provides complete hydrated lime solutions with stable performance, precise water control, high calcium content, and reliable automation.

Overview of Calcium Hydroxide Production Line
A calcium hydroxide production line is a set of industrial equipment that converts quicklime (CaO) into high-quality calcium hydroxide powder (Ca(OH)2) through a controlled dry hydration process.
Hydrated lime, that is recognized as calcium hydroxide, is used in industries such as environmental protection, water treatment, chemical processing, construction materials, and other industries that need stable alkaline conditions and uniform powdered materials.
Unlike the wet-process methods or lime milk systems, dry-process systems operate as an uninterrupted industrial calcium hydroxide production system that performs continuous dry digestion, exact water addition, and accurate powder separation.
The calcium hydroxide production line system aims to deliver complete quicklime hydration while maintaining minimum moisture levels, steady particle size distribution, and dependable extended operational performance.
A hydrated lime production line, which is well designed, integrates digestion of lime, using thermal energy, sorting of powder, and collection of dust into a compact and closed system.
With good control of the process and the flow of materials, the calcium hydroxide production line produces uniform fines, high specific surface area, and uniform chemical activity, all of which are critical to the industrial processes that follow.
Daswell powder develops calcium hydroxide production line solutions based on industrial dry process technology. Each system is designed according to raw material characteristics, target capacity, and application requirements, ensuring stable performance, environmental compliance, and efficient operation throughout the production lifecycle.

Core Engineering Design of Daswell Powder
- Finished Product: High product quality and high yield, making it ideal for large-scale production.
- Stable Production Operation: Utilizes a full negative pressure production system, ensuring smooth airflow and high safety.
- Easy Operation: The production line is highly controllable, facilitating operation and maintenance.
- Wide Range of Raw Materials: Can calcine fine-grained limestone, making full use of mining resources.
- Low Heat Consumption: The rotary kiln equipped with a vertical preheater at the kiln end fully utilizes exhaust gas to preheat the limestone, significantly reducing fuel consumption.
- Energy Saving: Can fully utilize industrial waste gases as fuel for lime calcination, such as blast furnace gas, calcium carbide gas, and semi-coke furnace gas.
- Advanced Design: The kiln head adopts an integrated design of a vertical cooler and kiln head cover, resulting in a small footprint, good sealing, and effectively preventing the uncontrolled emission of hot exhaust gases.
- Low Pollution: Excellent environmental dust collection, using a pulse bag filter for dust removal, with emission concentration less than 50mg/Nm³.
- High Level of Automation: The production system’s operation, adjustment, control, and alarm functions are centrally controlled by a PLC in the main control room, requiring fewer on-site operators and resulting in high labor efficiency.
