Portland cement P.-C. Aïtcin, in Science and Technology of Concrete Admixtures, 2016Abstract Portland cement is at the same time the fruit of simple technology and a complex science. It consist in firing at 1450 C very simple pulverized raw materials having a very specific composition to produce an intermediate product called Portland cement

1) alite size, as before. 2) C2S content , as before. 3) grinding aid. Cost 0.6-1.2 €/t, usage 150-400 g/t. As the cement particle gets smaller the pores disappear and no longer become a factor. Increasing the amount of grinding aid will make the cement easier to grind. Hard burning = hard grinding.

:Cement Clinker CompositionAlaurentStage 2: Grinding, Proportioning, and Blending. The crushed raw ingredients are made ready for the cement-making process in the kiln by combining them with additives and grinding them to ensure a fine homogenous mixture. The composition of cement is proportioned here depending on the desired properties of the cement.

· This raw meal is then heated in a kiln upwards of 1450 °C. This critical stage initiates chemical reactions, resulting in the formation of clinker, the material that exists right before cement. This process is very important for the next and final stage of cement production. Step Four: Grinding and Addition of Gypsum.

The clinker manufacturing process starts with the extraction of the raw meal from the homogenization silo to insure that the raw meal is stable and homogenized in order to produce consistent clinker quality. The preheating of the material takes place in pre-heater cyclones fitted with a pre-calciner fired with petroleum, natural gas or coal

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 function of the kiln system is to convert the raw meal into clinker in the most efficient way and to produce clinker with an optimal mineralogy for acceptable cement performance. Typical chemical analysis of raw meal, clinker, and select processing parameters are given in Table 3.1.2. Table 3.1.2.

· Particle Size Reduction: The primary purpose of clinker grinding is to reduce the particle size of the clinker. The raw clinker typically consists of clumps or nodules with varying sizes, which are not suitable for direct use in cement production. Grinding is essential to break down these nodules into smaller particles.

ProTIR is a thermographic vision system that allows you to quickly detect any clinker particles that have not cooled sufficiently, preventing potential fires or damage to the conveyor belt. In addition, by monitoring the temperature, ProTIR ensures that the cooling process is correct. The thermal imaging camera-based ProTIR system is operated

· Cement clinker is a solid material made during the production of Portland cement. It is formed by heating a mixture of raw materials, including limestone and clay, to high temperatures in a kiln. The resulting clinker consists mainly of four minerals: alite, belite, tricalcium aluminate and calcium aluminoferrite.

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.
