Rotary KilnFeatures and use
The
rotary kiln belongs to construction equipment. According to different material , the rotary kiln can be divided into :cement kiln, metallurgy kiln and limestone kiln. The cement kiln is mainly used for calcimine of cement clinker, there are dry and wet types. The metallurgy kiln is used in metallurgy industry and ironworks. for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry ; for calcimine of calotte and aluminum hydroxide in aluminum manufacturer; for claiming of chrome sand ore and chrome power ore in chemical plant.

Working Principle of Rotary Kiln
Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and combustion. Cylinder as heated pivoting part, made of high-quality carbon steel plate, is supported on the support device by type, and there is mechanical or hydraulic pressure catch wheel on the first or some gear in order to control the turning of cylinder. Gearing gyrate according to process-required rotating speed by ring gear in the middle of cylinder. Because of the need of installation or maintenance, the bigger rotary kiln has auxiliary gears, which makes cylinder gyrate more slowly. To prevent cold air come in and dust overflow, the reliable
calciner tail and head sealing equipment is installed on feed and discharge end.
