The raw material for lime production is a natural calcium carbonate (commonly known as limestone). The lime rotary kiln is a continuous rotary kiln that produces quicklime (CaO) by calcining limestone at high temperature. The rotary kiln consists of a shell, a supporting device, and a supporting device with retaining wheels, transmission device, movable kiln head, kiln tail sealing device, burner and other components.
Advantages
1. Save operating cost
The lime rotary kiln adopts a new combustion technology, which can make full use of fuel energy, improve combustion efficiency, reduce energy consumption and operating cost, and save operating cost for customers.
2. Low material cost
On the basis of the preheater, the cooler is used to make the lime temperature out of the cooler 80°C +, which is convenient for transportation and storage, and the secondary air entering the kiln can be preheated to above 700°C, reducing the number of moving parts and special material.
3. Good quality
The lime produced by the lime rotary kiln equipment has the advantages of strong chemical reaction ability, small bulk density, and large specific surface area. It is currently the most important auxiliary material for steelmaking, coking, and calcium carbide industries at home and abroad.
4. Energy saving
The application of new technology has greatly improved the utilization rate of fuel, no longer a large amount of pollution, and met the national environmental protection requirements. It is not only a kind of protection for the environment, but also meets the national development requirements of energy saving, emission reduction, low-carbon environmental protection.
5. High decomposition rate
The vertical preheater with advanced structure and low pressure loss can effectively improve the preheating effect. After preheating, the decomposition rate of limestone entering the kiln can reach 20-25%, and 10-15mm fine-grained limestone can be directly used.
6. Low energy consumption
Reliable combined scale seals at both ends of the rotary kiln. The air leakage coefficient is less than 10%. In addition, our company mostly chooses composite refractory materials to reduce radiation heat loss. The equipment is easy to maintain and low in energy consumption.
