What is the cement clinker? As we know, the cement production process is mainly divided into raw material preparation, clinker calcination, and cement grinding. Clinkeris the material produced in the calcination stage and is usually used as the binder in many cement products. In other words, it is a semi-finished cement product by preparing limestone, clay, iron raw materials, etc., in proper proportion, calcining them to partial or full melting, and finally cooling to normal temperature.

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.

In the cement production line, we usually set a preheater and a precalciner before the cement kiln. After raw meal enters the preheater, they will be heated to about 750 by the hot air blown from the kiln, and then enter the precalciner to mix with the fuel injected from outside so that the exothermic process of fuel combustion and the endothermic process of carbonate decomposition in the raw meal are carried out rapidly in a suspended state, so the decomposition rate of raw meal before entering the kiln can reach 90%. This kind of rotary kiln with preheater and precalciner is called a pre-decomposition kiln. If only preheater is set, we call it suspension preheating kiln.

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.

AGICO offers different types of cement kilns from 10-5000t/d with steady running, high efficiency and large output. We adopt the most advanced calcination technology so that the production investment of clinker is small and the income is high.

Clinker cooling is the final step in clinker production. This process aims to recycle heat, preheat the secondary air, and improve the quality and grindability of the clinker. Besides, the rapid cooling of the clinker in this process is convenient for cement storage and transportation.

Clinker cooler is also called cement cooler, which set behind the cement kiln for clinker cooling. In cement plants, we usually adopt the rotary cooler and grate cooler for daily production. Inside the cooler, hot clinker will direct contact with the cooled air blown from the air blower to realize fast cooling.

AGICO provides different models of rotary coolers and grate coolers. They are all made of high-strength and high-temperature resistant alloy cast steel and has the advantages of high efficiency and long service life. For your different capacity needs and layout design, we can customize the equipment most suitable for you.

What is Portland cement? Portland cement derives its name from Portland, England, in many cases, also called silicate cement. It is a kind of hydraulic cementing material made of calcium silicate cement clinker, limestone or blast furnace slag (less than 5%), and an appropriate amount of gypsum. At present, Portland cement has been widely used in residential construction, traffic construction, large-scale water conservancy construction, and civil engineering, etc.

For different applications, Portland cement is classified into various types. The ordinary Portland cement (OPC) refers to Portland cement containing 5 ~ 20% of active mixing material. The Portland cement with a higher proportion of admixture (more than 20%) usually named by the admixture, such as the Portland pozzolan cement, Portland fly-ash cement, Portland slag cement, etc.

The main components of Portland cement include calcium oxide (CaO), silicon dioxide (SiO2), aluminum oxide (Al2O3), and iron oxide (Fe2O3). They account for more than 95% of the total cement composition. In addition, there are other oxides like magnesium oxide (MgO), sulfur trioxide (SO3), titanium dioxide (TiO2), phosphorus pentoxide (P2O5), potassium oxide (K2O), sodium oxide (Na2O), etc., accounting for less than 5% of the total amount. These components that make up raw materials react at high temperatures and finally form compounds tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite. The tricalcium silicate and dicalcium silicate determine the strength of Portland cement, in which the tricalcium silicate mostly affects the early strength. Tricalcium aluminate causes the initial setting of Portland cement.

Portland cement has a high setting and hardening speed, high strength, especially its early strength growth rate. It is suitable for high strength concrete structures, prestressed concrete engineering, and projects with high early strength requirements.

The rich content of carbon disulfide in Portland cement leads to its high heat release, high release speed, and high strength in the early stage. If it is used in winter construction, freezing damage can be avoided.

Portland cement has the characteristic of strong alkalinity, high density, and strong carbonation resistance. When the steel bar is buried in an alkaline environment, a layer of gray passivation film will be formed on the surface, which can keep the steel bar from rusting for decades. Therefore, Portland cement is especially suitable for important reinforced concrete structures and prestressed concrete works.

A large amount of calcium silicate hydrate will be produced during the hardening process of Portland cement. As a result, cement stone has high density, less free moisture, and is not easy to produce dry shrinkage cracks. Therefore, Portland cement can be used in concrete engineering in a dry environment.

Portland cement mixture is not easy to bleed, and the density of hardened cement stone is large, so the frost resistance is better than other general cement. It is suitable for concrete engineering under repeated freeze-thaw action in severe cold areas.

Portland cement manufacturing process can be divided into 6 steps: raw material crushing, pre-homogenization, fine grinding, clinker production, cement grinding, cement packing, etc. In these processes, we need the assistance of different kinds of cement equipment, such as cement kilns, cement mills, and cement crushers. The specific manufacturing processes are as follow:

After cement raw materials are mined, most of them should be crushed into small particle sizes. Coal, the main fuel for cement production, also needs to be broken in advance. In this step, all of them should be crushed by special crushing mills and then be transported to the pre-homogenization yard by belt conveyor.

The pre-homogenization refers to the preliminary homogenization of cement raw materials and fuel raw materials through the application of scientific stacking and reclaiming technology in the process of material storing and taking. In this step, the stacker is applied to pre-homogenize and stack raw materials in layers. Then the scraper reclaimer takes out raw materials and sends them to the batching station helped by the belt conveyor.

After the raw material batching is completed, cement raw meals (calcareous raw materials, clayey raw materials, and a small amount of corrective materials) need to be further ground by raw mills to realize a certain fineness, appropriate chemical composition, and uniform structure so that they can meet the calcination requirements of various cement kilns. The frequently used raw mills include cement ball mill, cement vertical mill, Raymond mill, etc. The air-swept coal mill is used for coal grinding.

Clinker production is the most critical stage in the cement manufacturing process. At present, the new dry process clinker production technology is the most advanced clinker production method. It has the advantages of high efficiency, energy-saving, and high production quality. By this production method, the raw meal powder will be pre decomposed in cyclone preheater and calciner firstly, and then enter cement kiln to be calcined under high temperature. After that, the calcined clinker will be cooled by the grate cooler and stored in the clinker warehouse.

After calcination, the clinker needs to be mixed with gypsum and additives to meet the requirements of different properties. Then, they will be ground by cement mills to appropriate particle size, forming a certain particle gradation, which increases the hydration area and accelerates the hydration speed.

Cement packing is the last step in the cement manufacturing process. After the cement powder is discharged from the unloading system at the bottom of cement silos, they will be sent into the cement packaging machine by the bucket elevator. In the packing machine, they are packaged into bags and then be transported to different sales markets.
