Clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. We sell all types of Clinker in Grey and White. Grey Clinker is the most suitable for cement production types Cem I 42,5R, Cem I 42,5N, Cem II 42,5R, Cem I 52,5N, Cem II 52,5N, Cem II 32,5R and Cem IV 32,5R.
Large clinker nodules (Figure 2) are difficult to cool, transport and grind into cement. Clinker should ideally have a smaller average nodule size and a narrow nodule size range. More uniformly sized clinker is more evenly distributed into the cooler and has more consistent bed porosity, which enables more stable cooler and kiln operation. ...

The substance called clinker is dark gray as the color that appears after firing while cement is produced and it is called the material that resembles the image of marble. Its production occurs as a result of heating and combining the material …
3. White clinker. It contains 76% Alite, 15% Belite, 7% Tricalcium aluminate, no Tetracalcium Alumino-ferrite, and 2% free lime, but the composition can vary widely. The white clinker produces white cement that is used for aesthetic purposes in construction.
The task of entering the data on clinker and cement production is related to a mass balance which should be determined on at plant level. The following plant mass balance diagram will help you to obtain the requested values as required for correct calculations. Please also see the Protocol Guidance Document (Chapters 7.4 and 6.4).
Clinker is manufactured from raw materials and then ground into cement. Cement is hydraulically active and will react with water. This reaction is a chemical reaction that will generate heat and CSH gel which gives the set slurry its properties of a …
Jordi Payá, ... María Victoria Borrachero, in New Trends in Eco-efficient and Recycled Concrete, 2019. 13.2.1.5 Industrial wastes. Cement clinker dust (CKD) is a problematic waste derived from the cement industry which may cause some problems in clinkering kiln operations and cement performance. CDW has to be discarded despite its hydraulic properties due to high content of …
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 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.
The invention discloses a mechanical hand for grinding a cement clinker end face, which relates to the technical field of mechanical hands. The mechanical hand is provided with an upright guide barrel which is arranged on a support base through a support adjusting arm and is formed by connecting an upper guide barrel with a lower guide barrel; an elevating lever which can move …
Cement and clinker exports increased by 22.5 per cent YoY to over 8Mt in the year up to 15 March 2021, according to the latest data from the General Department of Vietnam Customs. In terms of value, there was a 14 per cent YoY rise to US$295m. However, average prices dropped 6.7 per cent YoY to US$36.40/t.

An apparatus for sintering cement clinker with a spouted fluidized bed granulating furnace and a fluidized bed sintering furnace is provided which includes a perforated distributor having a multiplicity of nozzle holes through which gas for granulating injected raw material for cement while spouting and fluidizing the same is introduced; a ...
This work assessed the properties of the hydration processes and the strength development of synthesised belite cement samples. The belite clinker was synthesized in the high-temperature furnace by calcining the mixture of industrial waste (~ 18%) (granite cutting waste and silica-gel waste from AlF3 production) and natural raw materials (~ 82%) at 1150 °C …
ILHAN TRADING. ILHAN TRADING was founded in 1995. The company is mainly active in trading Cement (white & Grey, in Bulk & Bags), Clinker in Bulk, Iron & Steel with various sizes and kinds, Metal, Aluminum, Bauxite, Slag, Fly Ash, Gypsum, Coal and Pet-coke. Along 24 years experience, the company has been handling the shipping and logistics related to the products.
As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...
Ordinary Portland Cement Clinker is the essential component in producing cement which is made by sintering limestone.In the manufacture of Cement, clinker formed by sintering or fusing without melting to the point of liquefaction, alumina-silicate materials such as clay and limestone during the cement kiln stage and happens as 3 millimeters (0.12 inches) to 25 millimeters …
As the temperature of the material increases, the mineral becomes a liquid phase and reacts to form a large amount (clinker). After the clinker is fired, the temperature begins to decrease. As a leading cement plant manufacturer, AGICO Cement supplies cement equipment for clinker plant, such as cement rotary kiln, preheater in cement plant ...
The diverter is 2,540mm tall with 900mm square inlets and outlets. The 1,524mm-tall interior chute is constructed of 19mm abrasive-resistant steel (400BHN). The body is constructed of 13mm carbon steel. The entire unit weighs 4,990kg. The Vortex Pivoting Chute Diverter was a perfect match for the customer's application.
The ability to sell cement (or clinker) in long distance markets not only brings the profits that go with the trade itself, but ensures a substantial reduction in production costs per tonne over the full production volume of the plant. Approximately 800-900Mt/yr of clinker and cement benefit from seaborne cement and clinker trade and distribution.

Clinker produced by early static kilns was in the form of large pumice-like lumps. Rotary kiln clinker on the other hand, because of the rolling action of the kiln, emerges as fairly regular roughly spherical hard nodules of diameter typically 5-50 mm, together with a certain amount of dust abraded from the nodule surfaces.. Clinker minerals react with water to produce the …
The cement production processes mainly include raw material crushing and storage, raw material proportioning and grinding, clinker calcination, clinker grinding, cement packing, etc. Portland cement is the most widely used cement in our daily life.
