The kiln must work continuously to ensure a steady regime and uniformity of the clinker. A conventional, larger kiln in a wet process plant produces 3600 tons of clinker per day. Cement manufacturing by wet the process is energy-intensive, so it is uneconomical compared to dry process and semi-dry process.

While each cement plant may differ in layout, equipment, and appearance, the general process of manufacturing portland cement is the same: crushed limestone and sand are mixed with ground clay, shale, iron ore, fly ash and alternative raw materials. ... Some manufacturers grind the raw materials dry, while others use a wet-grinding process ...

 — The slurry is introduced into a rotary kiln, a lengthy cylindrical boiler that rotates on its axis. The kiln consists of three zones: the upper zone, known as the preheating zone, where hot gases from the lower zone dry and heat the slurry; . the middle zone, known as the calcining zone, where a temperature of about 1500 °C is reached …

 — A gas flow rate of 400 ml/min, which provided an equivalent CO 2 flow rate to that in the CO 2-aided washing experiment, resulted in the best Cl-removal of 98.72% for CQ-A and 84.24% for CQ-B at 30 min. Compared with the ash washing behavior in the CO 2-aided system, similar Cl-removal results were obtained using the flue gas-aided …

 — Cement Manufacturing Process. Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.

 — Cement manufacturing process is a reliable bonding material. It is obtained by burning calcareous material (lime) and argillaceous material (clay) and then grinding, types of cement. The cement manufacturing process was first produced by Joseph Aspidin, a mason from England. As its color resembled a variety of sandstone found in Portland, …
