lime kiln process

The main component of limestone is calcium carbonate, while the main component of lime is calcium oxide. The basic principle of burning lime is to use high temperature to decompose calcium carbonate in limestone into quicklime of calcium oxide and carbon dioxide.

lime production

Limestone and fuel are loaded into the lime kiln (if the gas fuel is fed through pipelines and burners), after preheating, it begins to decompose at 850 °C, and completes calcination at 1200 °C; after cooling, it is discharged out of the kiln to complete the production of quicklime products. Different kiln shapes have different preheating, calcining, cooling and ash discharge methods, but several process principles are the same, namely: high raw material quality, good lime quality; high fuel calorific value, low quantity consumption; The calcination time is proportional; the activity of quicklime is inversely proportional to the calcination time and the calcination temperature.
