Detention Slaker – An efficient and stable quicklime digestion solution

In the industrial production process, digestion of quicklime (CaO) into slaked lime slurry (Ca(OH)₂) is one of the key steps. The retention slaker independently developed and manufactured by Cronus uses advanced reaction control technology to provide customers with efficient, stable and low-maintenance lime digestion solutions. It is widely used in water treatment, papermaking, metallurgy, chemical industry and other fields.
Product Introduction


Capacity: 15~50t/h
Detention Slaker is a continuously operating lime digestion equipment. By controlling a certain retention time (Detention Time) in the reaction tank, quicklime and water are fully reacted to generate uniform slaked lime slurry. The equipment is equipped with an automatic feeding system, a stirring system and a temperature monitoring device to ensure reaction efficiency and product quality.
Main features
✅ Efficient reaction: By setting the retention time, ensure the lime is fully hydrated and improve the utilization rate of slaked lime.
✅ Stable slurry quality: uniform reaction, controllable slurry concentration and particle size distribution, convenient for subsequent process use.
✅ Compact structure and reliable operation: fully sealed design, supporting automatic control system, easy operation and low maintenance cost.
✅ Wear-resistant and corrosion-resistant materials: suitable for high temperature and high alkali environment, longer equipment life.
✅ Energy saving and environmental protection: optimized thermal management system reduces energy consumption and effectively controls dust and emissions.
Application fields
💧 Municipal and industrial water treatment: pH adjustment, heavy metal removal, water softening
🏭 Papermaking industry: preparation of slaked lime in lime recovery system
⚙️ Metallurgical industry: steel desulfurization, ore flotation pretreatment
🧪 Chemical industry: preparation of alkaline raw materials, waste liquid neutralization, etc.
