Cement plant emerged in the process of development of different production methods and different types of rotary kiln, according to the raw meal preparation methods can be divided into dry process production and wet process rotary kiln production, and production method of limestone rotary kiln is divided into two types of dry-process rotary kiln and the wet rotary kiln.Because the kiln preheater heat exchange device, and can be divided into different types of kiln.In building material, metallurgy, chemical industry, environmental protection and many other manufacturing industries, turning round case of solid materials is widely used in mechanical, physical or chemical processing, this kind of device is called a rotary cement kiln.
Cement rotary kiln mainly has two kinds, one kind is kiln cylinder in horizontal (a slope), and can do rotary motion is called rotary kiln (also known as lime rotary kiln); Another kind of kiln shell is not vertical rotation is called shaft kiln. The type of wet process rotary kiln is widely Used for wet process in the production of cement rotary kiln wet method kiln, wet production is made from the raw water is 32% ~ 40% slurry. Due to the slurry preparation into liquid, so mix well among different raw materials, raw ingredients evenly, make the high quality of the clinker burning, it is the main advantage of the wet process rotary kiln.
In addition, Metallurgy chemical kiln is mainly used in metallurgical industry mills lean ore magnetization roasting; Chromium, nickel and iron oxidizing roasting; Refractory plant roasting high alumina bauxite ore and aluminum plant roasting clinker, aluminum hydroxide; Chemical plants such as ore roasting chromium and chromium ore minerals. Lime rotary kiln (i.e., active lime rotary kiln) used for roasting plant, ferroalloy plant with the active lime and calcined dolomite.
