Understanding the Cement Manufacturing Process

Jumbo Cement

Indian, being the second-largest producer of cement in the world, enjoys a huge demand from different industries. A cement manufacturing plant can grow with time if it has potential resources, including material and manpower. In India itself, the demand for cement is huge owing to several government projects introduced for infrastructure development, highway constructions, and housing society development.

If we talk about the cement industry, the raw material is procured or supplied by the Indian mining industry. As someone running a cement factory in India, one would know different varieties of limestone, such as lime shell, coral limestone, crinoidal limestone, onyx, and hydraulic limestone. 

Limestone is the main raw material used during the cement manufacturing process. It is found in the sedimentary rocks and is changed through the process of dynamic metamorphism that converts it into marbles. It’s surprising to know that many Indian states possess a reservoir of limestone, like Rajasthan, Gujarat, Madhya Pradesh, Andhra Pradesh, Telangana, and Meghalaya. 

Moving our focus from limestone, another important raw material used in the cement manufacturing process is coal. Why? Coal acts as an energy source as it is crushed and stocked, and taken out diagonally before grinding it. You may know the states having coal mines in India, i.e., Chhattisgarh, West Bengal, Madhya Pradesh, and Odisha. 

How is coal used in the cement manufacturing process? It is used to heat the raw materials at 1450 degrees centigrade. You will be surprised to know that if you use high-grade limestone variety in the cement manufacturing process, you would use low-grade coal for the same. If you’ve got experience working in a cement manufacturing plant, you may know about these things in detail.

Understanding the cement manufacturing process in detail

The first task that takes place during the cement manufacturing process is mining limestone. Take note that the limestone is crushed to 80 mm in size and excavated from open cast mines. Then it is taken out diagonally for the grinding purpose in raw mill hoppers. Upon receiving raw material from mines, limestone gets transferred to the raw mill to turn into a fine powder through the grinding process. 

Clinkerization is the process of heating the fine powder of limestone at 1450 degrees centigrade, as mentioned earlier. Then the produced clinker material is kept in an electrostatic precipitator to store it as a concrete silo. Then the pyro processing of kiln feed starts to produce cement clinkers. After that, these hot clinkers are cooled down for storage, and then gypsum and clinker are mixed for further grinding into a fine grey powder. Now, this fine grey powder is the cement that gets packed and sold in the market.
