Cement rotary kiln: rotary kiln is the core equipment of the clinker plant that is used for clinker burning. According to the cement manufacturing process, rotary kiln can be divided into two types, dryprocess cement rotary kiln, and wetprocess cement rotary kiln.
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres to 25 millimetres in diameter. It is produced by sintering limestone and aluminosilicate materials such as clay during the cement kiln stage.
The mixture inside the slightly inclined kiln is rapidly cooled from 2000#176;C to 100#176;C200#176;C. Thus, the final product, clinker, is produced, and then stored, ready for the production of cement.
Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
AGICO Cement is a cement plant equipment manufacturer committed to development and innovation. We can provide the production, transportation, installation and many other services of the equipment needed in the cement clinker production process. In addition, we also provide the construction of large cement plants. We are a trustworthy partner!
The grate cooler in a cement plant cools and transports the cement clinker from the rotary kiln, and provides heating air (secondary air) for the rotary kiln and preheater. The performance of the grate cooler will directly affect the production efficiency, energy consumption, and clinker quality of the kiln system. Grate cooler in the factory

Extraction and Preparation of Raw Materials. The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to preblending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly
Cement plant is necessary for cement production, mainly consist of a series of cement equipment apply for preparation of cement raw materials, clinker production, and finished cement production, such as cement mill, cement crusher, rotary kiln, cement roller press, cement dryer, clinker cooler, cement silo, and related cement plant equipment.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400#176;C1500#176;C in the rotary kiln.

The functional unit is the production of 1 kg of Portland cement strength class (CEM I R). Average fuel for clinker production is composed of #215; 10 3 MJ natural gas (high pressure), #215; 10 4 kg light fuel oil, #215; 10 2 kg heavy fuel oil, #215; 10
#0183;#32;After production, the clinkers were ground to 74 m for chemical composition analysis in accordance with the Chinese National Standard quot;Methods for chemical analysis of cementquot; (GB/T, 2008). To prepare the cement, the clinkers were mixed with 5 wt.% natural gypsum and were crushed to a specific surface of 400#177;10 m 2 /kg.
