Lime is the unseen ingredient in so many products that make up
the world today. Everywhere, from the houses we live in, to the
highways and airport runways we travel on, in the production
of iron and steel, glass, pulp and paper, sugar-refining,
agriculture, food and food by-products and more recently
environmental uses designed to improve air and water quality. W ‘n’ W is committed to a Quality Lime product that will meet
or exceed customer expectations. Because of this Commitment to
Quality we are able to deliver a reliable and consistent Lime
product
CALCINED
LIME High
calcium Quick Lime production requires a large amount of
heat, which is generated in the kiln environment. The
quarried and sized limestone travels through a rotary
kiln and is subjected to these high temperatures where
the calcium carbonate begins to dissociate with the
resultant formation of calcium oxide. The minimum
temperature for the dissociation of calcium carbonate is
1648oF (898oC).
HYDRATED
LIME High
calcium quicklime readily reacts with water to form
hydrated lime. The reaction is highly exothermic and the
process is known as "slaking".
The reaction is usually carried out in a "slaker"
(a specially designed mixer) which, through a process of
rigorous mixing, makes certain that all of the quicklime
has come into intimate contact with water and no
unreacted quicklime remains.
CALCINED DOLOMITE Dolomitic
quicklime is the name given to the quicklime formed from
calcining a natural dolomitic limestone that contains
nearly an equal molar weight percentage of calcium oxide
to magnesium oxide. Ideally, this quicklime would
contain 56% calcium oxide, 40% magnesium oxide, and 4%
other major lime impurities such as iron oxide, aluminum
oxide, silicon dioxide, and sulfur.
