Product Description

Production methods

1. Calcining limestone will coarsely crush the limestone to 150mm and screen the fine slag below 30 ~ 50mm. No bituminous coal or coke requires a particle size of less than 50mm, and the ash content of the low melting point should not be too much, and the addition of anthracite or coke is 7.5% ~ 8.5% (weight) of limestone. Will the screening of limestone and fuel timing, quantitative by join kiln kiln top, in 900 ~ 1200 ℃ calcination, then through the cooling for a quick finished products. Carbon dioxide is produced in the calcination process.

2. Dissolve the marble in pure nitric acid and boil it to remove the clean CO2. Add the lime milk to the hot solution, filter the hydroxide precipitates, such as Cu, Fe, Mg, etc., and heat the filtrate to produce Ca(HC) when it is near boiling.

O3) 2 and Ca (HC…


Lime can be used to make calcium carbide, liquid alkali, bleach, bleaching powder, and also used in tanning leather, metallurgy and purifying waste water.
