Active lime calcined rotary kiln advantage

ZK is a design and production and sales in one of the active lime rotary kiln manufacturers, the main features in addition to the production of lime quality and stability, there are the following advantages:
1. Rotary kiln production is high, suitable for large-scale active lime production line, can also be used by small and medium enterprises. ZK can provide a full range of rotary kiln equipment, the existing production of lime rotary kiln, the daily production capacity of 50-800 tons, the quality of many enterprises at home and abroad by the praise.
2. Rotary kiln is a simple structure of the open calcined kiln, can be timely discharge of sulfur combustion gas, and not vulcanized material adhesion, so that the product of low sulfur content to meet the requirements of steel. In addition, the material moves evenly and uniformly, the product is stable, the low expansion rate and the overload rate, and the rotary kiln can calcine the highly active lime and make steel. Under the same conditions, the activity of the lime produced by the rotary kiln is higher than that of the gas furnace (30 ml on average). Generally speaking, the lime is 340-380ml or even 400ml.
3. Rotary kiln can be directly calcined 10-50 mm of limestone. For general mines, 0-30 mm limestone that cannot be processed by another furnace accounts for 30-40% of the total output. And with the refinement of steelmaking raw materials, limestone in the sintering process is gradually replaced by quick lime, fine limestone cannot be used at the same time. The construction of the rotary kiln production line can not only utilize the high quality limestone mine, but also realize the sustainable development of the lime industry.
4. Kiln tail installation of vertical preheater equipment, can be fully used at high temperatures burning gas, in the normal temperature to the initial decomposition of the preheat limestone, can greatly improve the output of rotary kiln, unit of product heat.
5. Kiln installed vertical cooler equipment, not only can quickly cool high-temperature lime, improve product activity, and easy to transport and storage. You can also allow secondary air into the kiln at higher temperatures, which can effectively increase the calcination temperature in the kiln and reduce fuel consumption.
6. From the kiln vertical preheater discharge flue gas temperature is low, about 280-350 ℃, dust content is low 20g / Nm3 or so, so that the flue gas treatment tracking configuration to be simple and effective to successfully meet the environmental requirements.
