In the cement industry, the main chemical components of the most commonly used Portland cement clinker are calcium oxide, silica and a small amount of alumina and iron oxide. Its particles are usually of diameter 3-25 mm and dark grey. It can be stored for long periods in a dry condition without reduction of quality, thus it is traded internationally and used by cement manufacturerswhenraw materialsare found to be scarce.
The production of cement can be divided into dry process and wet process, while because of the high output, low heat consumption and steady running, the dry process has become the most commonly used manufacturing method in cement plant, mainly includes three models dry process rotary kiln production, suspension preheating kiln production, and pre-decomposition kiln production. Of these models, the clinker calcination can be divided into preheating and pre-calcining, clinker sintering, and clinker cooling three stages.
The preheating and pre-calcining of raw meal replace partial functions and shorten the length of the cement kiln. It improves cement production efficiency and reduces heat consumption.
The production process of preheating and pre-calcining makes the thermal layout of the calcination system more reasonable, improves the production efficiency and product quality, reduces the energy consumption, meanwhile, it also has more superior performance in many aspects such as environmental protection.
Cyclone preheater, also called suspension preheater, is the essential cement equipment in the preheating and pre-calcining process. Different from the stacked heat transfer mode in the rotary kiln, the material in preheater is in full contact with the hot air under a suspended state. Due to the large contact area, its heat transfer speed is fast and the heat exchange efficiency is high.
The five-stage cyclone preheater produced by AGICO merges preheater and precalciner into a single. It has a small space occupation and adopts the automatic control system to make the production process more convenient. For different areas and capacity needs, AGICO provides a custom-designed solution to your cement plant.
Clinker sintering is a crucial link in clinker calcination, which mainly occurs in the cement kiln. Inside the kiln, raw meals are heated by rising temperature and generate a series of physical and chemical reactions. When the temperature reaches its peak, the clinker will be produced by rapid cooling. These reactions can be expressed as follow.
Cement kiln is the main equipment for clinker sintering. From structure, it can be divided into rotary cement kiln and shaft kiln, while, from the working principle, it can be divided into the dry method and wet method kiln.
Cement production line is the production line of cement equipment consisting of a series of equipments. Mainly by crushing and pre homogenization, preparation of raw meal homogenization, preheating and decomposing, cement clinker sintering, cement grinding and packaging process.
CrushingDuring cement manufacturing process, the majority of raw materials, including limestone, clay, iron ore, coal, etc. will be crushed. Specifically, due to larger granularity and higher hardness, the crushing of limestone that is maximally consumed in cement process plays critical role in the raw material crushing.
Raw Material HomogenizationThe raw material homogenization system is the last guard to stabilize the constituent of raw materials.During cement manufacturing process of dry process of cement manufacturing, to homogenize the constituent of fed raw materials is the premise of stable clinker sintering.
Cement Clinker SinteringBeing completed preheating and pre-decomposition, the raw materials will be fed into the rotary kiln for clinker sintering.When the temperature rises up to about 1300, the solvent minerals will be liquidized. Then components such as C12A7, C2F and C2S dissolved in the liquid phase will react with CaO to produce a large number of clinkers.In the rotary kiln, the pre-decomposed carbonate will be further decomposed rapidly and experience a series of solid phase reaction, generating many solvent minerals.
According to various fuels and scales, we can offer pulverized coal combustion system, natural gas combustion system, and heavy oil combustion system to our customs so as to assure them of maximum benefit.nbspWhen cement clinkers sintering is completed, the temperature will decline, and the extremely hot clinkers discharged from the rotary kiln will be cooled by a cooler to a temperature the conveyors, storages and cement mills in next processes can bear. In addition, the sensible heat of the clinkers will be recycled so as to improve thermal efficiency and clinker quality.nbsp.
Cement packingCement packing cement factory has two kinds of bags and bulk shipping methods. The proportion of national standards required for bulk must reach above 70, and the development of bulk cement is a big trend in china.
