In the process of limestone calcination, the impact of the particle size of the raw material limestone is very large. Because the separation of CO, slowly proceeds from the surface of the limestone to the inside, the calcination of large-sized limestone is more difficult than small-sized calcination, and it takes more time. long.

Calcination is a thermal treatment process most commonly applied to inorganic products. In its most conventional meaning, the term "calcination" is widely used in industrial thermal processing terminology to describe the processes of burning the lime or converting the iron ores into oxides.

1. Rotary kiln preheater. Rotary kiln preheater is one of main engines of active lime equipment, main foundation of which is convey limestone materials sent from the upper part into the preheater and at the same time preheat materials evenly to about 900℃ in the preheater by high temperature waste gas (1150℃) exhausted from kiln after calcination.

Q: What is the process involved in flash calcination? TK: For customers dealing specifically with fine ores, we designed the Gas Suspension Calciner (GSC) technology – something we have supplied since the beginning of the 1970s. It consists of a series of preheating cyclones, a calciner vessel and a series of cooling cyclones.

· Calcination of CaCO3 is a highly endothermic reaction, requiring around 755 Mcal of heat input to produce a ton of lime (CaO). The reaction only begins when the temperature is above the dissociation temperature of the carbonates in the limestone. This typically is between 780 deg C and 1340 deg C.
