About Limestone

The main mineral component of limestone is calcite. It has rare crystal structure and mineral particles and its surface is smooth and granular. Colors are black, gray, white, yellow and brown. Limestone containing seawater formation lime, hence the name of marble, limestone, chalk, rock, etc. Their main component of natural mineral is calcium carbonate. Limestone calcinations line is widely used in the fields of building materials, metallurgy, chemical industry, environmental protection, etc.

Limestone Calcination

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. As a famous limestone calcinations line manufacturer, Xinguang provide lime calcinations line with reasonable limestone calcinations price.

The limestone in the pre-heater is heated to around 900 ° C by the kiln flue gas of 1150 ° C. At this time, about 30% 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 100 ° C by the cold air and then is discharged. The 600 ° 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.

Lime production line is composed of vertical preheated, rotary kiln, grate cooler, air treatment system, raw material conveyor system, finished product conveyor system, raw coal grinding system.
