"Lime" is also sometimes used to describe byproducts of the lime manufacturing process (such as lime kiln dust), which, although they contain some reactive lime, generally have only a fraction of the oxide or hydroxide content of the manufactured product. In this manual, "lime" means quicklime, hydrated lime, or hydrated lime slurry.
Hydrated Lime. Let's begin with hydrated. When limestone is burned to produce lime it releases CO2 gas. What remains is a highly alkali "quicklime." Quicklime alternatively known as "hot" lime is extremely reactive with water and can be dangerous to handle, transport or work with although it has its construction uses for experienced …

In many of these applications, hydrated lime, or calcium hydroxide (Ca(OH) 2), is used. This is produced by adding water to quicklime (calcium oxide, CaO). Initially forming a dry hydrated lime product, the further addition of water creates a hydrated lime slurry in a process known as slaking—the focus of this white paper. Publication Date:
Adding Hydrated Lime to Hot Mix Asphalt. Hydrated lime can be added to hot mix asphalts in a variety of ways. As a general rule, the application rate is one percent by weight of the mix. However, in cases where severe stripping is anticipated the application amount may increase. The most commonly used methods of addition are described below:

Apart from the lime hydrate production, the hydrators also serve to process other materials. During their production, quicklime was formed as an ingredient contained in these materials, for example as a result of a burning process, and such quicklime has to be transformed into hydrated lime before it can be further processed or put into stock.

for hydration, the process is called "Slaking." In this case, the resultant hydrate is in a slurry form. Lime manufacturers generally use the dry hydration process for producing powdered hydrated lime. Our discussion here is limited to lime slaking. The slaking process is normally done with considerable excess water ranging from 2½ parts water
An inherent component of handling & slaking pebble lime is the necessity to remove the inert grit material from the lime slurry that is a by-product of the lime slaking process. Chemco's grit separation stage is engineered to separate and remove grit from the lime slurry before it is pumped to process.
