Cement Production: Raw Meal Production in Steps Perfectly mixed, accurately fed without pulsation, and precisely weighed. The key word is quality! And this quality is achieved during cement production with exactly matched process steps. In the first stage, the raw meal is produced, as described below.
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 precurser for the production of 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 pyroprocessing. Step 4: Clinkerization Cement clinker is made by pyroprocessing of kiln feed into the preheaterkiln system.
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 ...

Jun 19, 2012· In 1992, the company purchased by Nishat Group of Industries solely. After privatization it name changed from SCCOP to D. G. Khan Cement Factory, before the establishment of expansion plant (new plant) in 1997. The cement was brought to this and either from Maple Leaf Cement Factory Mianwali and Zeal Pak Hyderabad and ACC Rohi.
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.
