How Cement Is Made
The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed.

2 Process Of Manufacture Of Cement - Wet Process Dry Process
Manufacturing of portland cement by dry process: The raw materials are ground separately and stored in hoppers. Raw materials are mixed in dry form forming a raw mix. Raw mix is then fed to a rotary kiln to a very high temperature where water and CO2 are absorbed. Hot clinkers are formed which are then cooled rapidly.
