Cement is essential product in constructions. So cement
manufacturing is always profitable. Cement Manufacturing is also
construction related business but it is a capital intensive.
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
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.
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 or 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 in all means. 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.
