Rotary kiln, also called rotary calcination kiln, is a slightly inclined rotating cylindrical heat treatment furnace. It can cause chemical reactions or phase changes by continuously calcining or sintering solid materials.
According to different materials processed, rotary kilns can be divided into three types:
According to the different processing materials, rotary kilns can be divided into three types:
1. Cement kiln: used for calcining cement clinker in wet and dry cement plants, such as quicklime, limestone, clay, gypsum, shale, etc
2. Metallurgical and chemical kilns: used for low-grade iron ore, zinc oxide, nickel iron ore, bauxite, lithium ore, chromium ore, nickel iron ore, magnesite and ceramic particles in steel plants, chemical plants and refractory material plants.
3. Lime kiln: used for roasting active limestone and lightly burned dolomite in steel plants, ferroalloy plants, and magnesium plants.

Cement Production:
Cement kiln is mainly used for calcining cement clinker, which is divided into two categories: dry production cement kiln and wet production cement kiln .
Metallurgical Industry: Metallurgical chemical kilns are used for magnetization roasting of poor iron ore in iron and steel plants, oxidation roasting of chrome-nickel iron ore, roasting of high-metallurgical ores in refractory plants and roasting of clinker in aluminum plants, etc.
Environmental Protection Field: Lime kilns are used for roasting activated lime and lightly burned dolomite, etc.
