Step 1: Quarry. For its raw materials, cement manufacturing uses minerals containing the four essential elements for its creation: calcium, silicon, aluminum, and iron. Most plants rely on a nearby quarry for limestone. The most common combination of ingredients is limestone coupled with much smaller quantities of clay and sand.
· In order to produce raw materials preparation, clinker and rotary kilns are widely used in cement plants. The objective of this study is to perform energy and exergy analysis of a raw mill (RM) and raw materials preparation unit in a cement plant in Turkey using the actual operational data. The RM has a capacity of tonmaterial hourly.

At cement plant, according to different raw materials preparation methods, cement manufacturing can be divided into the dry process (including semidry process) and wet process (including semiwet process). Next, we will discuss the wet process of cement manufacturing in details.
USE OF SECONDARY FUELS IN THE CEMENT MANUFACTURING: A CASE STUDY. mill in order to create an inert atmosphere. Under direct operation the raw mill is off and the kiln is using stored raw meal. Energy is saved by the two main heat integration couplings, (a) heating up of raw meal by the flue gases in the 4stage cyclone preheater. live chat
2 Raw Mill For new line TPA clinker production the requirement of raw Mix is about TPA. We require approx. TPH with 20 hrs. /day and 330 days running in a year. Thus we propose New Raw mill of capacity 425 TPH is which can be either Vertical roller Mill or Roller press based in order to obtain the proposed Clinker production.
