Manufacturing Process of Lime From Limestone Production Line

Manufacturing Process of Lime From Limestone Production Line

Merchandise description

Lime Rotary Kiln advanced composition, reputable rotary kiln lime kiln sealed at each finishes merged scales. Air leakage coefficient is less than ten% of the composite refractory content, in get to decrease radiation heat reduction.

The metallurgical roasting gear is composed of the kiln head, kiln human body and kiln tail. Among which, the kiln head is mostly utilised to discharge, with more substantial diameter than the kiln physique. The kiln human body is the principal component, which is normally as long as 30-150m. In addition, the kiln tail, the substantial component of Functions.
The new kind metallurgical rotary kiln is just constructed and provides a huge variety of superiorities these kinds of as easy and trustworthy procedure, small quick-dress in parts, high procedure fee, and premium completed goods.


Procedure description

Certified limestone (twenty ~ 50 mm) are lifted by bucket elevator to prime silo of preheater. There are two stage indicators (up and down) controlling the feeding volume, then they are divided averagely into preheaters’ person rooms. The limestone’s temperature rises to about 900ºC heated by kiln flue gasoline of 1150ºC, about 30% of them are decomposed, and they occur into the rotary kiln by hydraulic rod, the place the limestone decomposed into CaO and CO2. The decomposed limestone are set into the cooler, where its temperatures drops to 100ºC and introduced. The hot air (600°C) will occur to kiln right after heat trade, and combine with coal gasoline for combination combustion. The exhaust gas is launched by the blower into bag deduster by means of multi-pipe cooler, then into the chimney although exhaust blower.The limestone from the cooler will be transported to the limestone final merchandise silo by means of vibrating feeder, chain conveyer, bucket elevator, belt conveyer.

Application for Energetic Lime Rotary Kiln:

The metallurgical rotary kiln is largely employed in metallurgy business for roasting numerous mineral components. To be specific, it can be utilized in metal vegetation for magnetizing roast of lean iron ore and oxidizing roast of chromite and josephinite, in refractory content manufacturing unit for roasting high metallurgical minerals, in aluminum crops for roasting clinkers and aluminium hydroxide, and in chemical vegetation for roasting aluminum ore sand, chrome ore powder, and many others.

Structural Attributes for Lively Lime Rotary Kiln:

1. The kiln physique is manufactured of top quality carbon steel or alloy steel plate by indicates of rolling and computerized welding.

two. The tyres, using wheel and open up equipment of this roasting furnace are produced of alloy solid metal.

3. The slide shoe bearing functions huge hole and impossibility of grinding the shoe.

4. The cylindrical roasting kiln is made with a specific driving device which is composed of a difficult enamel reducer, a adaptable diaphragm coupler and a immediate present motor.

five. A hydraulic thrust roller is typically adopted.

six. The kiln head and tail are respectively characterized by metal leaf kind seal and air-restricted seal.

7. The metallurgical rotary kiln is outfitted with a lower speed driving device.

Primary rewards of lime plant/lime manufacturing line

one. Excellent high quality and large output, ideal for large-scale exercise of lime creation line and huge-scale production.

2. Stable generation, all the manufacturing with the adverse pressure, air flow and increased stability.

three. Basic composition, easy management and useful operation and servicing.

4. Fine grade limestone can be calcined, total use of mine resources.

5. Reduced warmth usage per unit of solution, set up in vertical kiln perheated kiln can consider edge of exhaust heat limestone, greatly minimizing the gasoline intake.

6. Making complete use of industrial waste fuel as a fuel for lime burning (such as blast furnace exhaust gasoline, acetylene tail gas, charcoal blue exhaust, and many others)

seven. Kiln head adopts the design and style of vertical cooler integrating kiln head cover. The development area is tiny, great sealing, successfully staying away from very hot squander gas emissions unsystematically.

eight. Environmental defense, the adoption of pulse bag filter dust accumulating dust, discharge concentration considerably less than 50mg Nm³ / and underneath countrywide emission regular (much less than 100mg/Nm³ )

9. Substantial automation stage, the adjustment of production technique procedure, handle and alarm adopts PLC to management in the handle centre place, reducing artificial and enhancing effectiveness.




In 2014 , a building material manufacturing unit from ZheJiang province of China bought a lime creation line with yearly output of four hundred,000 tons. The main tools contains φ4.0×60m rotary kiln, φ2.4×4.75m coal mill, 5000 m² bag sort dust collector. And all of these gear were made by CHAENG independently, and CHAENG presented installation and commissioning advice.



Founded in 1958 and positioned in HangCZPT, ZheJiang province, CHAENG with sixty-year experience in tools production handles an spot of 330,000 m2 and its annual manufacturing price is one billion yuan. The organization specializes in manufacturing tube mills, rotary kilns, vertical mills and large steel casting and can undertake the EPC projects of cement creation strains, energetic lime manufacturing strains, blast furnace slag/ metal slag/ nickel slag grinding crops, and its merchandise are marketed to a lot more than fifty nations around the world and regions in Southeast Asia, Central Asia, South Asia, North The usa, South The usa and CZPTpe.
