Manufacturing of Cement By Dry and Wet Process

Cement is a kind of powdery material. When properly mixed with water, it will turn into slurry. The slurry will gradually harden in air and glue together the granular or fibrous materials such as sand and stone firmly. It is widely used in all aspects of our lives, such as subway construction, bridge construction, and residential building construction. It is an indispensable part of our city. The production process of silicate cement also known as Portland cement is representative in cement production. It usually adopts limestone and clay as main materials.

The remaining material is in the form of small lumps known as nodules after the CO2 is released. The central part i. The size of the small and hard clinkers varies from 5 to 10mm. The original rotary cement kilns were called 'wet process' kilns. After the initial setting time of the cement, the cement becomes stiff and the gypsum retards the dissolution of tri-calcium aluminates by forming tricalcium sulfoaluminate which is insoluble and prevents too early further reactions of setting and hardening.

Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators. The excavated materials are transported to the crushing plant by trucks, railway freight cars, conveyor belts, or ropeways. They also can be transported in a wet state or slurry by pipeline. In regions where limestones of sufficiently high lime content are not available, some process of beneficiation can be used.
