How does a Lime Kiln Work

lime kiln manufacturer

A lime kiln is used for calcination of limestone (calcium carbonate) to produce quicklime also called burnt lime. And the chemical formula is CaCO₃+ heat = CaO +CO₂. Usually, the heat is around 900℃ , but a temperature around 1000℃ makes the calcination process more quickly. Of course, the temperature can not be too high … Read more

How Can Calcium Hydroxide be Made from Limestone

Limestone is a sedimentary rock abundant on earth, which is mainly composed of calcium carbonate (CaCO₃) and many other minerals. Calcium hydroxide is also called hydrated lime, lime hydrate or slaked lime, whose chemical formula is Ca(OH)₂and it is the product of  reaction between quicklime and water. Then how can limestone turn into calcium hydroxide? … Read more

Dry Grinding of Calcium Carbonate

dry grinding of calcium carbonate

Dry grinding of calcium carbonate means to obtain ground calcium carbonate powder by grinding slumps of limestone or marble, rather than the slurry version. To grind calcium carbonate in a dry way, a calcium carbonate plant often includes a set of machinery, such as grinding mill, conveying device, classifier, dust collector, silos and so on. … Read more

How to Produce Coated Calcium Carbonate

How to produce coated calcium carbonate

Calcium carbonate coating often refers to coating ground calcium carbonate powder with stearic acid to change the property of GCC powder. Stearic acid is water soluble, and will react with calcium carbonate particles to form a surface coating of calcium stearate. As a professional player in mineral processing areas, Daswell provides a high effective coating … Read more
