Why would I not want to simply buy lime slurry, rather than buying quicklime or dry hydrated lime (in bulk or bags) to make my own slurry?
For some purposes using a lime slurry is fine. However, there are a number of considerations to be aware of. First, consider that it takes 1.32 trucks of hydrated lime to equal a truck of quicklime (weight ratios). If the slurry were 20% solids, it would take 5.0 trucks of slurry to equal one truck of dry hydrated lime, or 6.6 trucks of slurry to equal one truck of quicklime. In addition, you will have to factor in the freight cost for hauling a truck with 80% water in it. Quicklime and dry hydrated lime arrive in pneumatic trucks, and the lime is pumped into silos. Slurry comes in a slurry truck, which is then pumped into an on site portable slurry tank, or slurry tank in the plant. The slurry has to be constantly agitated to avoid the settling of the lime. Another consideration involves the availability of slurry. All of the major lime companies produce quicklime and most produce dry hydrated lime. Only a few are involved with lime slurry, which limits the sources available. All of t
