Everyone knows that rotary kiln is widely used in metallurgy, chemical industry, building refractories, environmental protection and other industries. The cement rotary kiln is the main equipment of the cement clinker dry and wet production line. In this paper, the rotary kiln manufacturer Henan Hongxing Mining Machine analyzes the wide application of this equipment.
In addition to calcining cement clinker, cement rotary kiln is also used for calcining clay, limestone, and slag drying. In the production of refractory materials, rotary kiln equipment is used to calcinate raw materials to make it stable in size and increase strength. . In nonferrous and ferrous metallurgy, iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, files and other metals are smelted and roasted with rotary kiln as the smelting equipment. For example: it is used in the production of aluminum to roast aluminum hydroxide into alumina; it is used in ironmaking to produce pellets for blast furnace ironmaking; foreign "SL / RN method" and "Krupp method" are used to iron ore Direct reduction; chlorinated volatile roasting method is used to extract tin and lead. During the beneficiation process, a rotary kiln is used to magnetize and roast the lean iron ore, so that the original weak magnetism of the ore is changed to strong magnetism to facilitate magnetic separation. In the chemical industry, rotary kiln is used to produce soda, calcined phosphate fertilizer, barium sulfide, etc. This method has the advantages of low energy consumption, low power consumption, no sulfuric acid, and the use of low- and medium-grade phosphate ore, and it is quickly popularized.
In addition to the cement rotary kiln, it is doing a good job in environmental protection. Using the cement rotary kiln to burn hazardous waste and garbage, this not only reduces waste and harmless waste, but also uses waste as fuel, saves pulverized coal, and does To the recycling of waste.
