cement industry process

Clinker is the intermediate product used in the manufacturing of cement. 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.

This type of cement was invented in the early 19th century by Joseph Aspdin. It is named 'portland cement' because its property is similar to the stone quarried on the Ise of Portland, England. The making process of portland cement in the modern industry can be divided into the wet process, dry process, and semi-dry process.

cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass. Setting and hardening result from hydration, which is a chemical combination of the cement ...

The cement industry is the most important consumer of rubber waste. It uses 236,000 t of scrap tires (26 MJ/kg calorific heat) and 290,000 t of industrial waste (plastic waste, paper, textiles, etc., 22 MJ/kg caloric heat) (VDZ, 1999 ). Table VI.5.21 shows a comparison of components of traditional fuels and scrap tires.

Cement plants conduct frequent chemical and physical tests at each step of the manufacturing process to ensure compliance with industry specifications . These rigorous quality control measures ensure that the cement produced meets the required standards for strength, setting time, and other essential properties.

Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions.
