Your Guide to the Manufacturing Process of Cement

The manufacturing process of cement involves raw material procurement, preparation, proportioning & blending prior to heating, and formation of clinker. These small lumps are then ground into a fine powder and dispatched as cement. Cement is used as an adhesive in construction projects such as roads and buildings. It is a crucial resource for infrastructural development throughout all sectors of the economy. UltraTech Cement Ltd. is the largest cement supplier in the Indian market, while other big players include Ambuja Cement, Shree Cement, Dalmia Bharat Ltd., and Birla Corporation Ltd.

Raw Material Acquisition

In order to ensure that the raw material is of good quality, it is necessary to identify the requirements for your project and establish a reliable source of supply. You should also ensure that there are sufficient resources available for you to purchase the required quantities of cement as well as other raw materials within budget. A cement supplier may use different ingredients to achieve desired properties based on the individual requirements of each project. OfBusiness fulfills raw material requirements based on the requirements of a site at the lowest market rates.

Raw Material Preparation

After raw material procurement, the mixture is ground, mixed, and then kiln-dried to produce a cement paste. Raw materials include limestone, clay, and shale. These substances are crushed or pulverized before they’re mixed with other ingredients such as sand (which binds them together) and/or water. The mixture is then heated in an oven until it reaches around 1300-1550°C. This high temperature helps to melt the clumps of sand into liquid form, resulting in an ideal consistency for pouring into molds for use on buildings or other projects.

Raw Material Proportioning & Blending

The raw material is blended in different proportions depending on the type of cement being produced and its required strength, durability, and other properties. For example, if a cement supplier requires a lower-strength but good water resistance, their raw material procurement will include different ingredients when compared to higher load-bearing capacity requirements.

The finished product is called ‘clinker’ because it consists of tiny particles which are formed by caking together during drying or heating up under pressure in a kiln. This clinker is then ground down into a fine powder for use in various applications such as extrusion, casting, etc., which again requires different blending processes depending upon what is being manufactured from this clinker mixture.

Preheater & Kiln Feeding

The preheater and kiln feeders are used to feed raw materials to the cement plant. The preheater keeps the raw materials at a temperature of around 300°C in order to make them hydrate, while the kiln serves as a final step for drying, heating, and calcination of these raw materials.

Clinker Manufacturing Process

Clinker is the final product of the cement manufacturing process. It is a hard, brittle, porous mass of calcium silicates that can be used as a building material. The raw material procurement process generally includes sourcing limestone and clay. Clinker contains about 25% sand and 75% calcium carbonate (CaCO3).

Cement Grinding

Cement grinding is the process of grinding cement to a fine powder. This can be done using either mechanical or hydraulic methods, depending on the requirements of your project.

The mineral composition of cement varies from one manufacturer to another and may change seasonally depending on availability in nature. This means that you may need to order different types of crushers for your project depending on what type of materials are required for production.

There are two main types of equipment used for grinding: crushers and mills (also known as ball mills). Crushers are usually more powerful than mills, but they are more expensive because they have bigger motors with higher power ratings than mills do. A cement supplier may only use them when large amounts need crushing down into smaller particles ranging from 5 microns down to 2 microns.

Storage, Packing & Dispatch

Storage, packing, and dispatch of cement are done in warehouses. Once it has been stored for some time, the cement supplier packs it into bags which are then dispatched to the customer.

The storage process involves mixing raw materials such as limestone powder or sand with water and producing slurry by using a mixer machine. A cement supplier uses electric mixers that rotate continuously at high-speed to produce a uniform paste from the ingredients without any clumping of materials or lumps forming inside them during the mixing process.

OfBusiness assists across all steps of the raw material procurement process and caters to all scales of requirements with the top cement suppliers of the country. This allows us to deliver consistent, lower-priced products in smaller time frames right up to your project site.
