In Cement Industry raw meal blending or homogenization is always done in silos. It is the last beneficiation step in the line of the raw mix preparation processes installed with the aim to reduce the residual relatively short-term, high frequent compositional variations observed for the raw meal produced in the. 13.
Drive technology for the cement industry. Pre-blending hall Raw material silos Vertical roller mill Homogenization silo The entire cement manufacturing process producing up to 12,500 tons of clinker a day, requires superior performance and efficiency. The drive technology in use for the cement industry .
Jan 01, 1983 Raw material prehomogenization by using big stockpiles is widely used in the cement industry. An attractive alternative of raw material mixing is obtained by the use of an efficient control strategy together with a continuously operating homogenization silo.
There are several types of cement production processes dry, semi-dry, semi-wet, and wet, depending on the preconditioning process of raw. But nowadays, almost all plants are based on the dry process where the main stages are Feed stocks preparation this stage includes the process of siege, crushing, and pre-homogenization.

Raw Material Homogenization Reclaimer amp Stacker Manufacturing, Supply and Installation. Raw Mill Unit Manufacturing and Installation. Raw Meal Silo Mechanical Parts Manufacturing and Installation.
Vertical roller mill Homogenization silo Fine grinding performed by vertical mills Mills grinding raw materials to very fine grain are used at various stages in cement production. Due to their low energy consumption in comparison with conventional horizontal mills, it is preferable to use vertical mills that employ enormous drives.
Pre-homogenization Pre-homogenization is the proportional mix of the different types of clay, limestones, or any other required material. Raw material storage Each of the raw materials is transported separately to silos, where it later will be added in specific amounts according to the particular type of cement being produced.

Homogenization BLENDING In preparing raw meal, raw materials like limestone, clay and iron ore are proportioned and fed to raw mill, where these raw materials are ground and well mixed. However, this mixing is not enough to produce clinker of uniform quality.
Quality cement clinker production Compressed air is used widely for homogenizing the slurry or raw meal. The storage capacity of the section is designed to meet the requirement of the pyro - processing plant for 3 to 4 days.
Jan 20, 2016 1. Introduction. Over the last century, Portland cement-based concrete has become the highest manufactured product on Earth in terms of volume. Concrete is used worldwide as a building material and is the most consumed substance on Earth after water Sakai, 2009.The volume of concrete produced globally is approximately 5.30 billion m 3 per year Roskos et al., 2011, with more than
Cement grinding The clinker from the pyro-processing area is ground in ball mills or roll press Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are O sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 4000 Blaine surface cm2gm.

Aug 30, 2012 Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
Aug 01, 2015 Cement production, which is highly dependent on the availability of natural resources, will face severe resource constraints in the future. This is especially true for the cement industry in China.
Dec 20, 2011 The introduction of the homogenization process into the technological chain of manufacture of cement and mixture calculation, in accordance with the quality standards, allows us to find solutions. This study has shown that it is possible to manufacture all types of clinkers by respecting the technological constraints and the standards norms ...
