Lime Slurry Preparation and Precise Dosing System Lime is a commonly used chemical agent in water treatment, typically applied for the removal of sulfate, fluoride, phosphorus, silicon, arsenic, and acid neutralization. The DOSAMA lime slurry preparation and dosing technology, originating from Europe, integrates a complete set of equipment including powder storage, precision quantitative dosing, slurry proportioning, and metering pump-based accurate chemical injection.
This system exemplifies a safe and reliable integration of mechanical elastic scraper arch-breaking and quantitative conveying, effectively addressing critical challenges:
1.Impact of silo level variations on density;
2.Moisture absorption and caking of lime powder, as well as slurry sedimentation and scaling, while achieving dosing accuracy up to 2.5%.

Lime Slurry Preparation System Hydration Process Quicklime (CaO) reacts with water to form hydrated lime (Ca(OH)?) through a hydration process, releasing significant heat and expanding in volume. The theoretical water requirement for complete hydration is 32% of the lime's weight. Hydrated lime is a fine white powder with limited water solubility. Excess water yields a lime slurry (milk), where particles form a colloidal calcium hydroxide structure. The alkaline solution reacts with reactive silica or alumina at ambient temperatures to generate hydraulic binding compounds. Slurry Concentration Typical lime slurry preparation concentration: 10–15%. Preparation Methods 1.Slaking of Quicklime 2.Direct Hydration of Pre-Hydrated Lime |  |
