fitability of manufacturing system. In Nigeria, approximately 40 to 50 per cent of cement manufacturing cost is energy related; each tonne of ce- ment requires 60 - 130 kg of fuel oil or its equivalent and about 105 kWh of electricity, depending on the cement variety and process type employed [10]. Cement produc-
The proportioned raw materials and water are ground into cement raw slurry, and sent into wet process kiln to calcine clinker. The semi-wet process of dehydrating raw slurry, making raw meal block, and then calcining in the kiln can also be classified as wet-process cement production.
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). Cement-based structures constitute the largest surface area of all man-made structures (Odigure, 2009).

The processes used for the manufacture of portland cement can be classified as dry and wet. In dry process. The raw materials are first reduced in size of about 25mm in crushers and Crushed material is ground to get fine particles into ball mill or tube mill. Each material after screening is stored in a separate hopper.
Cement clinkerisation is the major energy-consuming process in cement manufacturing due to the high-temperature requirement. In this paper, energy data including specific energy consumption, forms, and types of energy used at different units of cement manufacturing processes were analyzed and compared for effectiveness, …
2.2 Production process There are four basic types of cement kiln processes currently in use. They are wet process, semi wet process, semi dry process and dry process. The kiln can be considered as the heart of the plant as it constitutes clearly the most important step in the process of cement manufacturing.
1. Wet process: In this process, the raw materials are changed to powdered form in the presence of water. In this process, raw materials are pulverized by using a ball mill, which is a rotary steel …
Various steps of manufacture of cement through the wet process are described below: Crushing & Storage Limestone and other calcareous materials are crushed and stored in silos or storage tanks. Clay and other argillaceous materials are mixed with water thoroughly in a wash mill and stored in basins.
Stage of Cement Manufacture There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite.
that of dry powders. The wet process also enables an easier control of the chemical composition of the raw mix. However, the wet process is more energy intensive and Fig. 1 - Simplified cement production process[5] Tab. 1 – Cement EU Standard and Composition [5] Types of cement Clinker Other Constituents CEM I Portland 95-100 CEM II

Cement production processes can be categorized as dry, semidry, semiwet, and wet processes depending on the handling of raw material before being fed to the rotary kiln. Nowadays, almost all new plants are based on the dry process and many old wet plants are also remodeled to dry or semidry processes.

Wet Process. The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally …
There are three processes in cement manufacturing plant [ 9 ]: raw material mixing, pyroprocessing (burning), and grinding. Raw material processing: this can be the wet process or dry process depending on the method of milling.
The following is a wet process of cement manufacturing step-by-step guide, 1. The raw limestone from quarries is first crushed into small size fragments. Then it is mixed with clay or shale in a ball or tube mill and ground to form a slurry of a fine consistency with the addition of water.
