The development of the “Twelfth Five-Year†building materials industry will enter a new stage of development, especially the cement industry. The past year has been a wonderful year for the Chinese cement industry, and it is also a year of harvest. The cement output reached 2.06 billion tons and the profit exceeded 100 billion yuan. This is not only the fastest growth rate, but also the increase. China's cement production. It has accounted for about 60% of the world. This is not only the pride of Chinese cement people, but also the global cement industry. The production process of cement is simply two mills and one burn, that is, the raw materials are produced by crushing, crushing, grinding and mixing to form raw materials. The raw materials are fired at a high temperature of 1450~C, and the clinker is crushed. Grind together with gypsum or other mixed materials to form cement. Since the raw material preparation has dryness and wetness, the production method is classified into a wet method, a semi-dry method or a semi-wet method, and a dry method. As a kind of equipment in industrial machinery, rotary kiln has a simple structure, a wide range of action, and has some principles of considerable dynamics. Some kiln bodies also have a certain drying effect. The rotary kiln equipment is composed of a cylinder body, a supporting device, a belt wheel supporting device, a transmission device, an active kiln head, a kiln tail sealing device, a coal injection pipe device and the like. The kiln body of the rotary kiln is inclined to the horizontal level. The whole kiln body is supported by the supporting wheel device, and has a retaining wheel device for controlling the kiln body to move up and down. In addition to the main drive, the transmission system is also provided in the main power source. The auxiliary drive device that can rotate the kiln body during breakage to prevent bending deformation of the kiln body, the kiln head and the kiln tail seal device adopt advanced technology to ensure the reliability of the seal. The rotary kiln calcination system produced by the company has passed the technological innovation. The most advanced hydraulic gear wheel device at home and abroad, the metering plunger pump with high measurement accuracy, the high-precision speed control valve and the contact graphite block sealing device are adopted in the system. And other domestic advanced technology. In order to improve the degree of automation, the kiln head uses industrial TV to look at the fire, the process simulates the fluorescent screen, and the calcination belt uses an infrared scanner to directly reflect the calcination of the calcined belt on the computer. These new technologies are intuitive to use, easy to operate, and reliable to use. . The thermal system has been stabilized, and the equipment operation rate has been improved. Compared with the equipment of the same specification, the operation rate has increased by 10%, the output has increased by 5%-10%, and the heat consumption has decreased by 15%.
