Solution description

Lime Rotary Kiln sophisticated structure, reputable rotary kiln lime kiln sealed at both finishes combined scales. Air leakage coefficient is significantly less than ten% of the composite refractory materials, in purchase to reduce radiation heat reduction.

The metallurgical roasting products is composed of the kiln head, kiln human body and kiln tail. Between which, the kiln head is largely utilized to discharge, with larger diameter than the kiln entire body. The kiln human body is the principal component, which is generally as long as thirty-150m. In addition, the kiln tail, the significant component of Characteristics.
The new kind metallurgical rotary kiln is basically built and presents a large range of superiorities this kind of as simple and reputable procedure, small rapid-put on parts, higher operation charge, and top quality finished products.


Approach description

Certified limestone (twenty ~ 50 mm) are lifted by bucket elevator to leading silo of preheater. There are two amount indicators (up and down) controlling the feeding amount, then they are divided averagely into preheaters’ individual rooms. The limestone’s temperature rises to about 900ºC heated by kiln flue gas of 1150ºC, about 30% of them are decomposed, and they appear into the rotary kiln by hydraulic rod, in which the limestone decomposed into CaO and CO2. The decomposed limestone are put into the cooler, in which its temperatures drops to 100ºC and launched. The scorching air (600°C) will arrive to kiln after heat trade, and mix with coal gas for combination combustion. The exhaust gas is launched by the blower into bag deduster by way of multi-pipe cooler, then into the chimney however exhaust blower.The limestone from the cooler will be transported to the limestone closing product silo by way of vibrating feeder, chain conveyer, bucket elevator, belt conveyer.

Software for Active Lime Rotary Kiln:

The metallurgical rotary kiln is largely used in metallurgy industry for roasting numerous mineral supplies. To be particular, it can be utilized in steel vegetation for magnetizing roast of lean iron ore and oxidizing roast of chromite and josephinite, in refractory substance manufacturing unit for roasting substantial metallurgical minerals, in aluminum plants for roasting clinkers and aluminium hydroxide, and in chemical vegetation for roasting aluminum ore sand, chrome ore powder, and so on.

Structural Attributes for Active Lime Rotary Kiln:

one. The kiln body is made of premium carbon metal or alloy steel plate by indicates of rolling and computerized welding.

two. The tyres, riding wheel and open gear of this roasting furnace are produced of alloy forged metal.

3. The slide shoe bearing features large hole and impossibility of grinding the shoe.

4. The cylindrical roasting kiln is designed with a unique driving unit which is made up of a challenging tooth reducer, a versatile diaphragm coupler and a direct current motor.

5. A hydraulic thrust roller is generally adopted.

six. The kiln head and tail are respectively characterised by steel leaf type seal and air-tight seal.

7. The metallurgical rotary kiln is outfitted with a low speed driving gadget.

Main positive aspects of lime plant/lime manufacturing line

one. Excellent top quality and large output, suited for big-scale exercise of lime creation line and massive-scale manufacturing.

2. Stable creation, all the generation with the negative strain, air circulation and greater security.

3. Straightforward composition, easy management and beneficial operation and upkeep.

four. Wonderful grade limestone can be calcined, complete use of mine sources.

5. Minimal warmth consumption per device of product, installation in vertical kiln perheated kiln can just take gain of exhaust warm limestone, drastically minimizing the gas usage.

6. Producing entire use of industrial waste gasoline as a gasoline for lime burning (this sort of as blast furnace exhaust fuel, acetylene tail fuel, charcoal blue exhaust, and so on)

7. Kiln head adopts the design and style of vertical cooler integrating kiln head go over. The construction area is small, good sealing, successfully staying away from sizzling squander gasoline emissions unsystematically.

8. Environmental protection, the adoption of pulse bag filter dust accumulating dust, discharge concentration less than 50mg Nm³ / and beneath countrywide emission normal (much less than 100mg/Nm³ )

nine. Substantial automation amount, the adjustment of production technique procedure, handle and alarm adopts PLC to control in the handle centre area, decreasing synthetic and improving performance.




In 2014 , a building content factory from ZheJiang province of China bought a lime creation line with annual output of 400,000 tons. The main equipment consists of φ4.0×60m rotary kiln, φ2.4×4.75m coal mill, 5000 m² bag sort dust collector. And all of these gear had been manufactured by CHAENG independently, and CHAENG offered set up and commissioning advice.



Founded in 1958 and found in HangCZPT, ZheJiang province, CHAENG with 60-12 months encounter in equipment production addresses an spot of 330,000 m2 and its annual generation benefit is 1 billion yuan. The company specializes in producing tube mills, rotary kilns, vertical mills and big metal casting and can undertake the EPC tasks of cement production traces, energetic lime generation traces, blast furnace slag/ metal slag/ nickel slag grinding plants, and its items are sold to more than fifty nations and regions in Southeast Asia, Central Asia, South Asia, North America, South The us and CZPTpe.

Our long-expression strategic companions: Arcelor Mittal, Tata Group, Pohang Iron and Steel Business, Germany CCE, Japan Chiba , ZheJiang Baosteel, Voestalpine and ASGT.
