Hydrated Lime Slurry: A very common product, also known as hydrated lime or CaO quicklime, lime can be ‘slurry-ized’ through the addition of water to dry lime powder. How to select the best valve for an abrasive slurry application to reduce erosion, cavitation or noise. Lime-Soil stabilization is the process of adding lime to the soil to improve its properties like density, bearing capacity etc. For LSD, lime slurry is prepared in a traditional lime slaker, where grit removal and lime recovery take place with high efficiency and then can be collected in an agitated tank for later use. Once, the water is evaporated or dried, the lime slurry produced is in solid form. We generally recommend peristaltic pumps or progressive cavity pumps, or any type of lime slurry pumps our customer feels confident using. Lime is normally stored as a dry powder and mixed with water or additional chemicals to create a lime slurry that can be pumped through pipes and added to the waste stream as needed. Lime slurry minimizes the problem due to the water added to the mixture. Hydrated lime is used in modern cement based mortars mainly for its properties as a plasticiser. Quicklime contains no water and is very caustic to the skin. Although it contains about 30% moisture, it is extremely dusty and requires special application equipent to distribute it on the roadway.
