CEMENT MANUFACTURING – A WET PROCESS WITH THE FLOW DIAGRAM. In the wet process, 1) The raw limestone from quarries is first crushed to small size fragments. Then it is mixed with clay or shale in ball or tube mill and ground to form a slurry of a fine consistency with the addition of water.
Aug 30, 2012· Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.

Raw Materials processing included: Setting and curing and cement manufacturing process, Process Discretion: Wet process, Semi-dry process, Dry process and Finish process.
So, the raw mix is burnt to produce clinker : the basic material needed to make cement. conveyor Raw mix kiln cooling preheating clinker storage at the plant Raw mill PowerPoint Presentation: THE CEMENT MANUFACTURING PROCESS 1.GRINDING : The clinker and the gypsum are very finely ground giving a "pure cement".
The milling process generates heat and excessive mill temperatures are undesirable. It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw .
Ball Mill Ball mills with high efficiency separators have been used for raw material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
This is achieved in a cement raw mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 μm diameter, and 5% of particles above 45 μm. The measure of fineness usually used is the "specific surface area", which is the total particle surface area ...
The process data collected from a local plant, Cimenta Cement Factory, in 2004, were used in model construction and testing. First, ANN (Artificial Neural
Chapter-3 Cement Manufacturing Process 36 3.1.3 Raw Material Grinding and Storage Material from the limestone and additive hoppers are fed to respective weigh feeders which weigh and feed the material as per the set ratio and quantity, which is then fed to the raw mill inlet with the help of belt conveyors. Two types of Raw
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
Extraction and Preparation of Raw Materials. The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to pre-blending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly .

The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.
