What Do We Understand About The Dry Process Of Cement Manufacturing?

 In dry and semi-dry processes for cement manufacturing, the raw materials will be crushed and then fed in the correct proportions. It is then added to the grinding mill. Then, the raw material will be dried and reduced in size to a fine powder in there.

The dry powder you will get there will be called the raw meal; then, the raw meal will be pumped into a blending silo. It is here where all kinds of adjustments are made. The proportions of the materials are fixed here as well. In short, the manufacture of cement is done in a silo.

Then the raw meal will be blended by passing compressed air to obtain a coagulated and uniform mixture. Compressed air will be induced upward. The upward movement of the powder will decrease the apparent density. The air will then be pumped over the quadrant of the silo. This will permit the heavier material from the non-aerated quadrants.

Therefore, the aerated powder that you will acquire will behave like a liquid. A uniform mixture will be obtained if it is aerated through the quadrants in turn for at least one hour. In some cement manufacturing plants like Surya Gold, continuous blending is used.

The blended meal then will be further passed through a sieve. After getting it through the drive, it will be fed into a rotating disc called a granulator. Finally, the quantity of water, about 12 % by weight, will be added to it to be blended into pellets.

What are the difference between Cement and Concrete?

The two materials Cement and Concrete are actually quite distinct both are used interchangeably. Concrete is created by mixing cement with other materials such as water, sand, gravel, and crushed stone while Cement is only a component of the concrete mix. Cement is often reserved for minor projects such as grouting or masonry construction. while Concrete is used to construct the majority of the structures you will come across because of its incredible durability. In This post we lookout the basic difference between cement and concrete. Basic Difference between Cement and Concrete Durability of Cement and Concrete  – Both concrete and cement are durable and tough but Concrete is always known for long lasting compare to cement. The oldest combination, in fact, is about 2500 years old. Cement will never be able to withstand the test of time like concrete, and it is prone to cracking when used alone. However, because of its adhesive properties, it is required in the concrete mix. We co

Difference Between PPC and OPC Cement based on it's application

 PPC (Portland Pozzolana Cement) and OPC (Ordinary Portland Cement) are the two types of cement in the construction industry. Both PPC and OPC have their unique properties and applications that make them suitable for specific construction purposes. Application of PPC Cement: PPC (Portland Pozzolana Cement) is a type of cement which is made by the combining silica, alumina, iron, gypsum, and pozzolanic materials. PPC Cement improves the durability and strength of the cement and making it suitable for use in specific construction applications. Five common applications of PPC cement: Dams and bridges: PPC cement is widely used in the construction of dams and bridges due to its high strength and durability. These structures are subject to heavy loads and constant exposure to water, and PPC's properties make it resistant to chemical attacks and long-term durability. High-rise buildings: PPC cement is also commonly used in the construction of high-rise buildings due to its high compre
