Features of lime rotary kiln compared with shaft kiln

Lime rotary kiln, as the leader in calcining active lime, has been deeply loved by lime manufacturers. The invention of the lime rotary kiln also led to the rapid development of the cement industry. Rotary kiln is used in many fields. Compared with traditional shaft kiln, lime rotary kiln has a high degree of mechanization, specifically in the following aspects: 1. Compared with the countercurrent single-tube mechanized wet material shaft kiln, rotary kiln calcining metallurgy or active lime, the unit product heat loss is low. 2. The calcination process of active lime rotary kiln has a high mechanization degree, the operation process is easy to control, and the production volume is large. It is suitable for the needs of large industries such as metallurgy and smelting. 3. Lime rotary kiln calcining system has many mechanical equipments and heavy weight. Therefore, the unit product consumes a large amount of steel and has a high investment. Rotary kiln equipment covers an area of large. 4. The material wears in the active lime rotary kiln, have a lot product powder, and there is a certain requirement for the raw material strength. Some raw materials are calcined in a shaft kiln to obtain better block lime, while calcination in a rotary kiln may produce a large amount of powder, resulting in a low yield. 5. In the process of calcining the active rotary kiln, the material is in the tumbling state, the heating is even, the temperature of the combustion device is easy to control, the calcining quality is good, the lime product activity degree can reach 350-400ml, and the lime pollution is small, which is favorable for obtaining high-purity lime. 6. Active lime rotary kiln can calcine raw materials with smaller granularity and can improve the utilization of raw materials. Because the raw material size is small, the product can be directly used in converter steelmaking without crushing. The invention of lime rotary kiln made many people have a new understanding of the application of rotary kiln, but also because of the extensive application of lime rotary kiln makes it become the company's core rotary kiln equipment. The mechanized production line has greatly reduced manpower and material resources, resulting in a higher degree of scaled production and sufficient protection for improving the efficiency of the enterprise.
