The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017). Cementbased structures constitute the largest surface area of all manmade structures (Odigure, 2009).

In order to reduce the manufacturing costs for cement, it is very important to optimise the existing mill installations as far as the grinding process is concerned and also to use high quality spare parts and consumables like grinding media. Ball mills are predominantly used machines for grinding in the cement .
Wet process. 1 Mixing of Raw materials in wash mill with 35 to 50% water. 2 Materials exiting the mill are called "slurry" and have flowability characteristics. 3 Size of the kiln needed for the manufacturing of cement is bigger. 4 Raw material can be mixed easily, so .
The process out clinker is cooled and ground to a fine powder with the addition of about 3 to 5% of gypsum. The material produced by this process known as Portland cement. The cement manufacturing is done by majorly by two methods known as wet process and dry process depending on their mixing is done with water or without water.
