Cement kiln is applied to carline cement clinker, which has two types,dry-type cement production kiln and wet-type cement production kiln. Metallurgy and chemical kiln is mainly used to magnetizing roast lean iron ore, oxidation roast the nickel chromium iron ore in the steel and iron plant.
Chemical rotary kiln is mainly used for metallurgical plant of iron and steel industry lean iron ore magnetizing roasting; chromium, nickel ore oxidizing roasting; refractory material factory roasting high aluminum soil vanadium ore and alumina roasting clinker, aluminum hydroxide; chemical plant roasting chrome ore and chrome powder minerals.
The slurry is fed into the upper end of a rotary kiln, while at the lower end of the kiln, a very intense flame is maintained by blowing in finely ground coal. The slurry slowly moves down the kiln and is dried and heated until it reaches a temperature of almost 1500 degrees Celsius producing "clinker".
A dry process kiln might be only 70m long and 6m wide but produce a similar quantity of clinker (usually measured in tonnes per day) as a wet process kiln of the same diameter but 200m in length. For the same output, a dry process kiln without a precalciner would be shorter than a wet process kiln but longer than a dry process kiln with a ...

For many years, rotary kilns have been used across various industries to drive chemical reactions by thermal processing.Rotary kilns have become very established in fields such as cement, lime, and minerals. Because these thermal processing tools have been used almost exclusively in these industries, they have been designed to meet the needs of these particular materials.
Rotary kiln for cement industry is mainly used to calcine cement clinker, and can be divided into two types, including dry-process rotary kiln for cement production and wet-process rotary kiln cement production.

At the present time some 80% of the global cement clinker production is obtained from dry kiln processes. However, there are still a several hundred wet process kilns in use (Eckert and Hand 2002; De Beus 1999).Modern dry process plants are a combination of a four-to-five-stage cyclone preheater and a pre-calcination followed by a short rotary kiln.
