This is where MERRICK’s experience in the design and manufacture of lime feeding and lime slaking systems comes into play. For economic reasons, on-site conversion of CaO, calcium oxide (also called quicklime or pebble lime) is preferred to purchasing hydrated lime.
Calcium hydroxide slurry is a suspension of calcium hydroxide in water. The calcium hydroxide or lime slurry results from the mixing of dry hydrated lime with water in a mixing tank equipped with a slurry agitator.. The resulting product is a lime slurry which has a concentration (lime to water ratio) that varies from 0.5% to 30%.

When there is a relatively low volume consumption required, Hydrated Lime Systems provide a more cost-effective solution compared to a Slaking system as the equipment is simpler and does not need to be designed to contain the exothermic reaction that takes place when slaking pebble lime.
A given amount of hydrated lime occupies far more volume as a dry powder than it does after mixing with water. Thus, when lime is measured as a dry powder, less is actually put into the mixture than is used if the lime is measured as putty. When wetted, dry hydrate lime will typically contract, on average, to 75% of the original dry volume.
Chemco's Quicklime Slaking System utilizes pebble lime's higher neutralization capacity based on tonnage to provide storage, dry feed, slaking of quicklime, and the delivery of the resultant hydrated lime slurry to the process point.
CAL~FLO slurry is made with air-classified hydrate, making it the highest grade raw product that lime mines produce. It also eliminates the application challenges of dry lime. In Burnett’s manufacturing process, CAL~FLO further cleans the hydrated lime slurry producing a high-quality lime slurry–one of the best in the market.
DRY-SLAKED LIME To construct towns and cities at the rate required in the late 18th century, Gerard Lynch, the historic brickwork consultant, has convincingly argued that most lime must have been made on site and used immediately, without waiting for it to mature. Dry-slaking is ideal for this: lumps of fresh quicklime are slaked with a limited ...
LIME SLAKING Lime slaking is the process of converting quicklime to hydrated lime (CaO + H20 -> Ca(OH)2) with the use of water. This chemical reaction is an exothermic reaction which denotes that during the reaction, heat is expelled from the slurry which produces some steam.
Aug 01, 2017· Hydrated lime, also known as calcium hydroxide lime (Ca(OH)², is available in white powder form and can be mixed directly in solution tanks and employed in dry form. Hydrated lime is commonly used as a primary coagulant for the treatment of industrial waste streams and contributes to the clarification of water.
A typical dry scrubber equipped plant spends between $1 million and $4 million per year; at these plants, lime expenditure is one of the plant's largest operating costs for a consumable material, second only to fuel. Recent experience has shown that lime slaking process optimization can reduce lime consumption by as much as 40%.
alleviate this cost, on-site slaking or hydration is the ideal solution. The Series A-758 lime slaker provides for reliable, efficient slaking of various grades of quicklime (CaO) at a substantial savings over other slaking methods. Through the pioneering use of paste-type slaking technology, the Series A-758 lime slaker consistently produces a
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca 2. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed, or slaked with water. It has many names including hydrated lime, caustic lime, builders' lime, slack lime, cal, or pickling lime.
Nov 24, 2017· In a killan (Furnace) Limestone's are transformed into Quick Lime (CaO) , which is kind of white in color and soft than stone. If you add water to quick lime what you get is slaked lime and the process is called slaking. CaO + H2O -> Ca(OH)2 (Slak...
Lime mortar is composed of lime and an aggregate such as sand, mixed with water.The Ancient Egyptians were the first to use lime mortars. About 6,000 years ago, they used lime to plaster the pyramids at Giza.In addition, the Egyptians also incorporated various limes into their religious temples as well as their homes.
DRY CHEMICAL FEED SYSTEMS Series A-758 Plus Lime Slaking System The A-758 Plus Lime Slaker system provides reliable, efficient slaking of various grades of quicklime (CaO) at a substantial sav-ings over other slaking methods. Our paste-type lime slaker produces a higher strength and more reactive paste resulting in more efficient use of lime.
Aug 18, 2015· Slaked lime is also called pickling lime as it is used for making pickles and hydrated lime. Slaked Lime Traditional Uses: Slaked lime is used to regulate the pH levels of soil, for whitewashing, in certain hair preparations, dentistry, as a natural …
May 22, 2013· In the video above, we show how we use hot mix (or dry slaking) method to make lime mortar in our Permaground RasJebal Farm, to build the stone stemwall of …
A lime slaking and addition system can consists of two systems to control the pH in the rougher and cleaner flotation circuits.A pebble lime silo will dose dry lime to the SAG mill feed belt; a hydrated lime make down system will provide slurry lime to multiple addition points in the flotation circuit.
An Overview Of Lime Slaking And Factors That Affect The Process By: Mohamad Hassibi Chemco Systems, L.P. November 1999 Revision 1 – February 2009 ABSTRACT Since lime slaking is an integral part of treatment systems in water, wastewater, air pollution, and process industries, its performance will influence the overall effectiveness
Besides the lime slaker itself, Sodimate can also supply the complete “upstream” storage and feed system. We engineer fully integrated dry storage and handling equipment for quick & hydrated lime, lime milk, and lime slurries, with uses ranging from water treatment to glass fabrication to road construction.
Our dry lime hydration plant constitutes a system in which quicklime is slaked in a continuous process with just enough water for powdery hydrated lime to be produced.

Mar 14, 2014· Hydrated lime (calcium hydroxide) is produced by adding a controlled amount of water to quicklime, a process commonly referred to as “slaking.” Because hydrated lime contains chemically-bonded water, approximately one-third more hydrated lime is typically required to dry the soil.
The main differences between hydrated lime and quicklime are their reactivity & their chemical composition. Hydrated lime and quicklime are both calcium compounds. In its hydrated state, calcium is called calcium hydroxide, and in its pure state it is called calcium oxide, or quicklime.. Calcium oxide has a heavy density (65lb/ft³) and is more reactive than hydrated lime.
Effect of Slaking Water Temperature on Quality of Lime Slurry By: Mohamad Hassibi Chemco Systems, L.P. July, 2009 There is a recent debate regarding the impact heated slaking water has on the quality of the slaked lime. This debate has caused a lot of confusion in the industry. The purpose of this paper is to clarify fact from fiction.
