With a production capacity of 100 to 1200t/d, the material is fed into the preheater's top storage bin via a discharge chute. Simultaneously, the hightemperature flue gas introduced by the rotary kiln heats the material to over 1000°C, causing partial decomposition of the limestone. Hydraulic push rods sequentially push the material into ...

Lime mud is a byproduct produced in pulp mills as part of the process that turns wood chips into pulp for paper. The pulp mill cooks wood chips with sodium hydroxide to extract the wood fiber used to make paper from the lignin that binds the wood together. During this process, sodium hydroxide is converted to sodium carbonate. The pulp mill than adds calcium oxide, also known as quicklime, to ...
