1, Rotary Kiln forComplete baking system of Calcining limestone

A Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include:

Cement , Lime , Refractories, Metakaolin, Titanium dioxide , Alumina , Vermiculite , Iron ore pellets

The rotary kiln produced byGood heavyhas strong structure, stable operation, high-quality products from the kiln and so on advantages, we can also offer advanced efficient shaft pre-heater, five grade cyclone preheater.

A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate). The chemical equation for this reaction is: CaCO3 + heat → CaO + CO2

2. Limestone rotary kiln Working process of Calcining limestone

Qualified limestone stores in silos and be shipped through the pre-heater by the elevator into the silos which is on the top of the pre-heater. The pre-heater on the top of silos is consisted of top and bottom level meter controllers which control the feeding capacity. Then through the feed tube the limestone is distributed to the indoor compartment of the pre-heater.
The limestone in the pre-heater is heated to around **0 ° C by the kiln flue gas of ***0 ° C. At this time, about *0% of the limestone has been decomposition. Then the limestone is put into the rotary kiln by the hydraulic stem. In the rotary kiln the limestone sinters and decomposes into CaO and CO2. Then the decomposed limestone goes into the cooler and is cooled to about **0 ° C by the cold air and then is discharged. The **0 ° C hot air after heat exchange goes into the kiln and combusts with gas. The Exhaust gas blended with the cold wind go to the bag filter through the suction fan and then through the exhaust fan into the chimney.
The limestone out of the cooler enters into the lime storehouse through the vibrating feeder, chain bucket conveyor, bucket elevator and belt conveyor. Whether to carry out screening and other procedures depends on customer requirements.

3, Structure of Limestone rotary kiln

The basic components of a rotary kiln are the shell, the refractory lining, support tyres and rollers, drive gear and internal heat exchangers.
