· 2.1 Portland Cement Clinker Burning. The main goal of the clinkering process is to produce the material of designed phase composition, which is called Portland cement clinker. Under the action of high temperature, parallel to the clinker phases formation, underwent the process of sintering and nodulization of material in the rotary kiln.

There are two primary processes used to manufacture clinker: the dry process and the wet process. Our plants use the dry process, which is more energy efficient. In the wet process, the raw materials are mixed with water to form slurry, which is fed into a kiln. Fuel costs are greater in the wet process than in the dry process because the water

The amount of liquid that can form is conventionally calculated using the Lea and Parker equation: at 1400°C, the amount of liquid produced is given by: L 1400 = 2.95 Al 2 O 3 + 2.2 Fe 2 O 3 + M. where M is equal to the %MgO if MgO<2%, otherwise M = 2. The final reaction which occurs during clinker formation, and requires the peak temperature

Explanation: While clinker is an important component in the production of cement, it is not a type of cement itself. Cement is made by heating limestone and clay in a kiln, and concrete is made by mixing cement with water, sand, and gravel. While cement and concrete are related, they are not interchangeable terms.

This paper considers the dry clinker production, which is the most used process in Brazilian production of cement (Kihara and Visedo 2014). A rotary kiln in a dry cement production can be divided into five zones (Stadler et al. 2011): heating zone, calcining zone, transition zone, firing zone and cooling zone.

· Clinker is challenging to grind down into fine powder due to its high temperature and rapid cooling during production, causing it to harden and form lumps. This hardness makes it difficult to achieve the desired fineness required for cement production, leading to increased energy consumption and grinding costs.

Reactions which take place as the feed passes through the kiln are reviewed below. They can be considered under three broad headings: Decomposition of raw materials-temperatures up to about 1300 °C. Alite formation and other reactions at 1300 C-1450 °C in the burning zone. Cooling of the clinker.
