Cement Production an overview ScienceDirect Topics
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. Typically, there are two processes of Cement manufacturing Dry process and Wet process. This blog shall discuss the process of manufacturing of Cement by wet and dry process.

In cement: Manufacture of cement manufacture are known as the wet, dry, and semidry processes and are so termed when the raw materials are ground wet and fed to the kiln In this paper we are discussing wet and dry process of Portland cement manufacture. Wet process minerals are wet ground to form a slurry and in dry process minerals are dry ground to form a powder like substance. In this paper, we are discussing the comparison between wet process and dry process with various advantages and disadvantages.Comparison of Wet Process and Dry Process of Cement

Wet Process of Cement Manufacturing Cement Wet
The procedures of the wet process are basically the same with the dry process, which can be divided into three stages: raw materials preparation, clinker calcination, and the cement grinding. All of these stages are kiln and the following operations will be similar to the wet process. The equipments used in the dry process kiln are comparatively smaller. The process is quite economical. The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 350 kg for producing a ton of cement in the wet process.Cements University of Babylon

Wet Process an overview ScienceDirect Topics
The wet process. The raw material is ground in water (30-40 % of water) and treated in a long kiln (up to 250 m). This process has practically been discontinued. Only one plant was using this process in 2001, among 20 cement plants that were operating in France. •. The semi-wet process.In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter.11.6 Portland Cement Manufacturing US EPA

A Review on Pyroprocessing Techniques for Selected Wastes
The wet and dry manufacturing processes are the two main ways of manufacturing cement . The major difference between wet and dry process is the mix preparation method before burning clinker in the kiln. The wet process involves the addition of water to the raw materials to form rawslurry which is thick.This process was especially evolved to counter the main drawback of the wet process i.e. high fuel consumption. In this process, the raw materials ground in dry condition are homogenized and then nodulised in a pan noduliser of dish or rotary type by adding controlled quantity of water (10- 12 %).CEMENT MANUFACTURING PROCESS AND ITS SELECTION: WET PROCESS AND DRY

The main advantage of dry process cement production is low heat consumption, it’s advantages include nonuniformity of raw meal, dusting, high power consumption. Wet process of cement. The proportioned raw materials and water are ground into cement raw slurry, and sent into wet process kiln to calcine clinker.Each bag of cement contains 50 kg or 0 m3 of cement. Figure 1. Flow Chart of Wet Process for manufacturing of cement. 1. Difference between Dry Process and Wet Process. If we consider the quality and rate then wet process is better and if we consider fuel consumption and time of process then dry process is better.

While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter.In the dry process, fuel consumption is lower as compared to the wet process. The dry process is, therefore, preferable if the raw material components are not too wet or sticky. As a fundamental rule, the dry process is to be recommended for reasons of heat economy, 1 particularly in cases where the raw materials contain less than 15%–18% water.Dry Process an overview ScienceDirect Topics

Cement Production an overview ScienceDirect Topics
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).
