Besides, the cement can be shipped in bulk 1.5 mt of big bags and 50 kg craft paper sacks packed in sling bags. Bursa Cement uses the most modern technologies. Some of these are; - Bursa Cement Factory has 3 POLAB AOT systems for online analysis of the raw meal downstream of the raw .
The components of the raw meal react at high temperature (900-15000C) in the precalciner and in the rotary kiln, to give cement clinker. Finish grinding of clinker and mixing with additives is done after cooling. Cement manufacturing consists of raw meal grinding, blending, precalcining, clinker burning and cement grinding.
Raw meal is fed into one end of the kiln, either directly or via a preheater system, and pulverized coal is burnt at the other end. The raw meal slowly cascades down the inclined kiln towards the heat and reaches a temperature of about 1 450 °C in the burning zone where a process called clinkering occurs.

The heated raw meal now enters the kiln where the gas temperature exceeds 2000 °C, where it is transformed into a molten mixture inside the rotating kiln. At the temperature of 1450 °C the minerals in the raw meal undergo chemical reaction to form a new compound known as Clinker, which is the pre-curser for the production of cement.

CEMENT Summit Materials has split its 13 operating companies into 3 segments: East, West, and Cement. Our Cement segment is comprised of Continental Cement Company, with 2 cement plants and 8 distribution terminals along the Mississippi River. Above is a photo of one of our cement plants, with details showing how cement is made. Cement [.]
Raw meal extracted from the silo, now called kiln feed, is fed to the top of the preheater via an air lift called the Poldos for pyro-processing. Step 4: Clinkerization Cement clinker is made by pyroprocessing of kiln feed into the preheater-kiln system.

However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the ...
in raw meal silos Before being burned in the rotary kiln, the material from the blending bed and the aggregates are ground to a fine raw meal in large mills. The powdery material is then transported to the silo by a pneumatic conveyor system. Reliable monitoring of the level is essential for optimal raw material storage. VEGAPULS 69

Inside, at 1400 degrees C, the raw material is transformed into clinker: small, dark gray nodules 3-4 centimeters in diameter. 9. Cement milling. The clinker is ground by different-size steel balls while it works its way through the mill's two chambers, with gypsum being added to extend cement setting times. 10. Cement packaging and shipping
The raw mix normally contains 95% limestone and 5% laterite. The raw materials are crushed to around 20-25 mm size and the proportioned raw materials are ground in a ball mill in dry condition to a very fine powder. The resultant product is called raw meal and is stored in concrete silos where it is pneumatically homogenized to get a uniform ...

This is achieved in a cement raw mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the "specific surface area", which is the total particle surface area ...
