Lime Kiln is the ideal equipment to produce quicklime by the calcination of limestone (calcium carbonate). We could provide technological solutions and complete production equipment for 50-800TPD quicklime (active lime) production line.
With 60 Years development, we gained different approaches of lime production process, such as energy saving rotary lime kiln process, traditional long rotary lime kiln process, mixed burining vertical lime kiln process, low heat value gas vertical lime kiln process, high heat value vertical lime kiln process etc. Usually, it has two types: lime rotary kiln and lime vertical kiln.
Based on the exprience accumlation of equipment manufacturing and technical improvements, during 2003-2005, we successfully developed a new pre-heater for dolomite and limestone calcining. This kind of new pre-heater brings a decrease of fuel consumption by 40% and output rise by 30%, and can recycle the heat from the exhaust gas and control the dust emission below 50mg/m³. At present, our company has taken a great effect on the limestone and magnesium industry. Our equipments have become preferred choice of the lime and magnesium experts.




China Energy Saving Lime Making Factory Main advantage:
1. Good quality and high output, suitable for large-scale activity of lime production line and large-scale production.
2. Stable production, all the production with the negative pressure, air flow and higher security.
3. Simple structure, easy control and beneficial operation and maintenance.
4. Fine grade limestone can be calcined, full use of mine resources.
5. Low heat consumption per unit of product, installation in vertical kiln perheated kiln can take advantage Of exhaust warm limestone, greatly reducing the fuel consumption.
6. Making full use of industrial waste gas as a fuel for lime burning (such as blast furnace exhaust gas, Acetylene tail gas, charcoal blue exhaust, etc)
7. Kiln head adopts the design of vertical cooler integrating kiln head cover. The construction area is small, Good sealing, effectively avoiding hot waste gas emissions unsystematically.
8. Environmental protection, the adoption of pulse bag filter dust collecting dust, discharge concentration Less than 50mg Nm³ / and below national emission standard (less than 100mg/Nm³ )
9. High automation level, the adjustment of production system operation, control and alarm adopts PLC To control in the control centre room, reducing artificial and improving efficiency.
