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.

During the process of cement production, 3 tons of materials at least are needed to be ground to produce one ton of portland cement. these materials include various raw materials, fuels, clinkers, mixtures and gypsum. according to statistics, over 60 cement plant power will be consumed to grind materials in dry process cement production line.
This method is called a semi-dry process, which belongs to the cement dry process production. advantages as the dry process is to directly feed raw material powder into the rotary kiln for calcination, and the moisture content of raw materials is about 1 2, it saves the heat consumption needed for the moisture evaporation.
