Method for producing quicklime using oyster shell powder and lime sludge
The present invention relates to a method for manufacturing quicklime which comprises the following steps: mixing an oyster shell powder, a limestone sludge, and dust to manufacture a blended raw material; and charging the blended raw material to a sintering furnace and performing a sintering process, so that the hydration rate of the blended raw material is 90% or more and 100% or less, and the differentiation rate of the blended raw material is 14 to 16%. The present invention has the advantage of stably supplying quicklime with stable quality and high quality.
