Limestone and other recurring raw materials are normally received in the plant in the size between 1 and 2 mm from the quarry. The production of a mixture of raw materials with a maximum size of approximately 0.2 mm occurs by breaking down the dimensions of the raw materials coming from the quarry. The reduction ratio at which these raw materials must be 1000-2000: 0.2 (Innovations in Portland Cement Manufacturing,2009). This breakdown of raw materials is difficult to achieve through a one-step operation. Therefore, after the reduction phase it is necessary to ensure that the raw mixture has good homogeneity to obtain a higher quality product and increase the efficiency of the plant. Stocks must be built up regularly to ensure continuity of the production process at various points. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get Original EssayThe process flow for preparing raw materials is a multi-step process and involves the following stepsCrushing is the basic process which involves reducing the size of raw materials and this process is carried out by in-house mechanical equipment to the factory. Crushing is performed in three stages: Product Name Size Size Range (mm) Coarse Taller 200-150 Intermediate Medium 70-40 Fine Small 25-5 Compression, friction, impact combined or individually affect the crushing process in a combination or each individually. The primary reduction of raw materials in a cement plant is carried out using crushers, i.e. single or double rotor or impact crushers. In case of hard raw materials, other types of crushers called jaw crushers are used, to break down abrasive materials, jaw crushers are used along with roller crushers. The need to pre-homogenize the raw materials in a cement production after secondary processing and crushing is very important because it standardizes the materials as their chemical composition varies. Limestone and aluminosilicate components are the main raw materials for which this unit operation is performed. Another name for pre-homogenization systems is "mixing beds". The ratio between the significant input chemical parameter of a given reservoir (Sin) and the standard deviation of the output parameter for the same reservoir (Sout) is known as the melting effect (H). Melting effect (H) = Sin/Sout measurement Homogenization effects greater than 1:10 are not possible as inaccuracies occur during the analysis and sampling of lumpy materials. However, in practice, the mixing efficiency of these systems is within the required range (Innovations in Portland Cement Manufacturing, 2009). Two types of grinding, namely dry and wet grinding, further crush the premixed raw materials into a fine mixture. The most common type of grinding used is dry grinding since the wet grinding process requires high energy consumption, which leads to excessive energy usage costs. Ball mills are mainly used all over the world for the grinding process. These mills consist of rotating cylinders filled with steel balls, as the material to be ground enters these cylinders due to the friction of the grinding balls present in them there is an impact on the material and grinding takes place. The peak use of ball charge energy for fine grinding determines the production and efficiency of ball mills (Innovations in Portland Cement Manufacturing, 2009). The main stage in the production process of.
