Cement Manufacturing

Cement Manufacturing

Cement Manufacturing: Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. Cement Manufacturing is also construction related business but it is a capital intensive.

Sell Cement Competitive Price: You can sell cement at competitive price because of the massive construction works that is going on. Before starting this, you should have a project plan with comfortable capital of your own.
Summary of production process: Cement is made from limestone and clay. Raw materials are extracted from the quarry crushed to powder and then blended in the correct proportions.

Blended Raw Material: This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln at a temperature of about 1500 C. The rotary kiln is a tube up to 200 metres long and perhaps 6 metres in diameter, with a long flame at one end. The raw feed enters the kiln at the cool end and gradually passes down to the hot end, then falls out of the kiln and cools down.
Clinker Store: The material formed in the kiln is described as 'clinker' and is typically composed of rounded nodules between 1mm and 25mm across. After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.

Get a Better Understanding of Cement: To get a more complete and integrated understanding of how cement is made, have a look at the Cement book or Ebook is easy-to-read and concise book also contains much more detail on cement and concrete chemistry and process.
Ebooks are also available in internet: Otherwise you can get it in bookstalls also. Please have a proper bookish knowledge basically, then only take initiative. Get experience in other plants also about their process system will help you to gain good knowledge.

Get licenses from Concern Authorities: You can get basic license details in internt through google search. In your near by city, if you go to MSME (Micro, Small, Medium Enterprises) center, you will get all details and booklet also available there.
What are the raw materials of cement: The most important raw materials for making cement are limestone, clay and marl. These are extracted from quarries by blasting or by ripping using heavy machinery.

Step-by-step process to Start a Cement Factory: Make a proper plan and analysis of cement factory.
Prepare a budget estimate based on your cost benefit analysis.
Select the market or region which you want to target.
Select location for good raw material supply.
Understand the cement manufacturing process.
How cement is manufactured by dry process: In dry and semi dry processes for manufacturing of cement, the raw materials are crushed and fed in the correct proportions into a grinding mill. The raw materials are dried and reduced in size to a fine powder in to grinding mill. The dry powder is called the raw meal. The raw meal is pumped into a blending silo.

Basic raw material for cement industry: Limestone comprises 95% of core raw material for cement production. Cement manufacturing consumes minerals such as gypsum, Quartz, bauxite, coal, kaolin (china clay) and iron ore too in varying amounts.
What are the two methods of manufacture of cement: From the limestone quarry to the delivery of the end product, follow every step in the cement manufacturing process.
Step 1: Mining. Step 2: Crushing, stacking, and reclaiming of raw materials.
Step 3: Raw meal drying, grinding, and homogenization.
Step 4: Clinkerization. Step 5: Cement grinding and storage.
Step 6: Packing.

How much should I invest for cement factory: You will require making an initial investment between Rs 50,000 to 5 lakhs as a security deposit and other requirements to the company, based on the brand you pick up. Usually, these companies will return this money to you with an applicable bank interest.
What is mini cement plant: Mini cement plant is a new cement plant, also known as a small cement plant, which refers to the cement plant with a clinker capacity of 50-500tpd.

Which process is the best for manufacturing of cement: Why Choose Dry Process From Manufacturing Cement Methods. Dry process cement kiln is a kind of rotary kiln which is mainly used in calcining cement clinker. The cement clinker made by the dry process has better quality and stability. It can bring more economical and social benefits in production.
What is the basic input in cement industry: Cement Sector - Industry Inputs. It is the main raw material required for production of cement. About 1.5 tonnes of limestone is used in the manufacture of 1 tonne of cement. Cement grade limestone is located only in certain areas in the country leading to establishment of cement plants in clusters.

What are the 5 types of cement: Ordinary Portland cement is the most widely used type of cement, which is suitable for all general concrete construction.
Portland Pozzolana Cement (PPC)
Rapid Hardening Cement. Quick setting cement.
Low Heat Cement. Sulfates Resisting Cement.
Blast Furnace Slag Cement. High Alumina Cement.
What is cement and its properties: Three types of strength of cement are measured compressive, tensile and flexural. Various factors affect the strength such as water-cement ratio, cement-fine aggregate ratio, curing conditions, size and shape of a specimen, the manner of molding and mixing, loading conditions and age.

What is natural cement: Natural cement is hydraulic cement made from limestone that has a high clay content (argillaceous limestone). The resulting powder is natural cement, which will set when mixed with water, and hardens through a process of cement hydration.
