Cement production is an important part of modern industry, in which rotary kiln technology is widely used in the production of cement clinker. Rotary kiln is an important thermal equipment, which can realize high temperature reaction of cement raw material and produce clinker. It is an indispensable equipment in cement production.
With the continuous development of science and technology and the progress of industry, the rotary kiln technology is also constantly improved and improved to meet the different cement production needs and environmental requirements. This paper will introduce the development history, advantages and disadvantages of rotary kiln technology, and look forward to the development trend of this technology in the future.
Rotary kiln technology first appeared in 1970s. At that time, the rotary kilns were mainly used for firing Cretaceous and other ores, producing building materials and chemical raw materials. At the beginning of the 20th century, with the development of industry and the rise of cement production, rotary kiln technology has been gradually applied in the field of cement production. The original rotary kiln mainly used direct heating. The fuel is natural gas or coal. The high temperature gas generated goes directly into the kiln to heat the cement raw material.
Cement rotary kiln website believes that with the progress of technology and the improvement of environmental protection requirements, rotary kiln technology is also constantly improved and improved. At the end of 1960s, the application of new technologies such as preheater and cyclone separator greatly reduced the energy consumption of rotary kiln, and greatly improved the production efficiency and product quality. In the 21st century, with the wide application of computer technology and automation technology, rotary kiln technology has gradually realized digitalization, intelligence and automation.
