November 21st Jiangsu Pengfei group Limited Co.,Ltd is in a busy, the workers for the export of Egypt 5 sets of 5.4 * 52 meters rotary kiln delivery preparations. After several months of overtime work, the high quality of the final completion of 5 sets of 5.4 x 52 meters rotary kiln manufacturing.
The rotary kiln calcination equipment made by PENGFEI Group through technological innovation, using the most advanced hydraulic damper device, the metering plunger pump, measurement of high precision high precision speed control valve and the contact type graphite block sealing device and other advanced technology in this system. In order to improve the degree of automation, kiln head adopts industrial TV fire process simulation screen, calcination zone using infrared scanner to calcination calcination zone is directly reflected in the computer, the use of these new technologies, intuitive sense, convenient operation, reliable use. Compared with the same specification equipment, the operation rate is increased by 10%, the output is increased by 5%-10%, and the heat consumption is reduced by 15%.
Rotary kiln is also used for calcination of clay, limestone and slag drying. Refractory materials are calcined in rotary kiln to make it stable in size, strength increased, and processed again. In non-ferrous and ferrous metallurgy, iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, file and other metal rotary kiln for smelting equipment, the ore, concentrate, intermediate, such as sintering, baking. For example, aluminum hydroxide is calcined into alumina in aluminum production; iron ore is used to produce pellets for blast furnace ironmaking; foreign SL/RN method and Krupp method are used for direct reduction of iron ore; chloride volatilization roasting method is used to extract tin and lead. During the ore dressing process, the rotary kiln is used for magnetizing roasting of the poor iron ore, so that the original weak magnetism of the ore is changed into strong magnetism, so as to facilitate magnetic separation. In the chemical industry, with rotary kiln production of calcined soda, phosphate, barium sulfide etc.. It has the advantages of low energy consumption, less power consumption, and the use of low and medium grade phosphate rock, and has been vigorously promoted. In the aspect of environmental protection, the cement kiln is used to burn hazardous waste and garbage to realize the harmless disposal of waste, and the waste is used as fuel to save coal powder, so as to realize the resource utilization of waste.
