Description

Technical Field

[0002] Cement kilns are mainly used to calcine cement clinker, which are divided into two categories: dry process cement kilns and wet process cement kilns. Metallurgical and chemical kilns are mainly used in the metallurgical industry for magnetization roasting of lean iron ore in steel plants, oxidation roasting of chromium and nickel iron ores, roasting of high metallurgical ores in refractory plants, roasting of clinker and aluminum hydroxide in aluminum plants, and roasting of chromium ore sand and chromium ore powder in chemical plants. Lime kilns (i.e. active lime kilns) are used to roast active lime and light-burned dolomite for steel plants and ferroalloy plants.

[0003] The centerline of the rotary kiln cylinder is an important installation parameter of the rotary kiln. Whether the centerline deviation meets the requirements is related to the stress of the kiln cylinder and the supporting wheel, and whether the rotary kiln can operate safely and smoothly. Therefore, accurate measurement of the centerline deviation is also very important.

The utility model is ingenious in conception, compact and reasonable in structure, and the connecting seat, movable support rods and other accessories are all detachable structures, which are convenient for disassembly, transportation and storage.
