Lime kiln is the core equipment of the active limestone rotary kiln production line. Independent innovation and development of new kiln type and new technology, reasonable allocation of lime kiln and large scale of lime kiln are important approaches to scale and specialization of lime industry. Compared with other types of lime kilns, rotary kilns have large production capacity, high product activity, stable quality, strong adaptability to raw materials, fuel ash pollution to the product is small, high degree of automation, simple control system, easy to operate, high productivity and kiln structure is simple, smooth flow, sulfur flue gas can be discharged in time, sulfur content in fuel is not easy to adhere, Therefore, the sulfur content of the product is low, in line with the requirements of steel, and occupy a very important position.

Construction scope of active limestone rotary kiln production line: It includes raw material storage system, feeding system, rotary kiln calcination system, waste gas treatment system (reserved denitration system), finished product storage, crushing screen dispersed loading system, finished powder and ash pneumatic conveying system, desulfurizer pulverizing system, environmental dust removal system, water supply and drainage system, circulating water system, PLC automatic control system and instrument detection system, communication system, monitoring system, fire department And so on.

The design guidelines and main principles of active limestone rotary kiln production line:

(1) Adopt mature and reliable new processes and technologies, so as to be technologically advanced, economical and reasonable, practical and reliable.

(2) Implement the national environmental protection policies, pay attention to environmental protection, adopt efficient dust removal facilities, make it meet the national and local environmental standards.

(3) All dust removal ash recycling. In the design, the transfer and drop of materials should be reduced as far as possible. The dust collection of all dust points should be divided into regions, and the relevant national environmental protection policies and standards should be strictly implemented to meet the emission standards.

(4) In the selection of equipment, on the basis of the principle of "reliable and practical, saving investment, advanced technology, energy saving and consumption reduction", try to unify the specifications and models, so as to facilitate production management and reduce the types and quantities of spare parts.

There are a large number of lime production enterprises in our country, but their technical equipment level and product quality are uneven. With the increasing awareness of energy saving and emission reduction and the introduction of corresponding national environmental protection policies, there will certainly be a large number of high energy consumption, high pollution lime enterprises will be eliminated. In recent years, the production line of large-scale activated limestone rotary kiln has been rapidly recognized and popularized by the market for its advantages of output, quality, energy consumption, land area, investment, automation control, energy saving and emission reduction, which is in line with the development trend of large-scale and energy-saving metallurgical lime industry, and has broad application prospects.
