Rotary kiln is the calcining kiln (commonly known as rotary kiln), which belongs to the device class materials.. Kiln according to different materials can be divided into cement kiln, metallurgy chemical kiln and lime kiln. Cement kiln is mainly used for calcining cement clinker production of dry and wet cement kiln cement kiln production of two categories. Metallurgy chemical kiln is mainly used in metallurgical industry, steel plants depleted iron ore magnetic roasting; Chromium, nickel, iron ore roasting; High alumina refractory bauxite ore roasting plant and aluminum roasting clinker, aluminum hydroxide; Chemical chromium ore roasting and chrome ore and other minerals. Lime kiln (ie active lime) for firing steel mills, ferroalloy plant with active lime and light burned dolomite.
Structure Features of Rotary Kiln:
Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and fuel device.
As a heated pivoting part, cylinder is made of high-quality carbon steel plate and supported on the support device by wheel belt. There is mechanical or hydraulic pressure catch wheel on the first or several support device in order to control the turning of cylinder. Gears make cylinder rotate according to process-required rotating speed through the ring gear in the middle of cylinder. Because of the need of installation or maintenance, the bigger rotary kiln has auxiliary rotary gears, which makes cylinder gyrate more slowly. To prevent enter of cold air and dust overflow, the reliable kiln tail and head sealing equipment are installed on feed and discharge end.
Application of Rotary Kiln:
Rotary kiln is commonly used in the production process of catalytic agent, molecular sieve and zinc oxide, etc. As a result, you can find a rotary kiln in variety of industries, like steel annealing and nonferrous smelting industries, metallurgy and chemistry fields, and building industries, and more.
Rotary kiln system, which is also called a rotary calcine kiln, is a commonly used building material machine. Classifying by material properties, a rotary kiln falls into cement kilns, metallurgy chemical kilns, and lime kilns.
