  • Cement clinkerWikipedia

    Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage. Cement In the cement manufacturing industry limestone or dolomite raw materials require grinding twice before the final cement product can be packaged and sold. Initially the process is a typical crushing and screening application.

    Grinding Mill For Raw Materials And Cement Clinker Cement. For raw materials and cement clinker the vertical roller mill is an excellent grinding solution because of the relatively lower cost of installation ease of operation and maintenance energy efficiency. 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.

  • QatranaProduction ProcessQatrana Cement Company

    Portland Cement is made primarily from a combination of a calcareous material such as limestone or chalk and of silica and alumina found as clay or shale.The manufacturing process consists essentially of grinding the raw materials into a very fine powder mixing them intimately in a predetermined proportion and burning them in a large rotary kiln at a temperature of about 1400 ˚C (2550 ˚F). A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln which transforms it into clinker which is then ground to make cement in the cement raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished

    Step 2 Proportioning Blending Raw Grinding. The raw materials are analyzed in real-time using cross-belt analyzers and in the plant laboratory blended in the proper proportion and then ground even finer. Plants grind the raw materials with heavy wheel-type rollers that crush the materials into powder against a rotating table. Very fine grinding produces a fine powder known as raw meal which is preheated and then sent to the kiln. The material is heated to 1 500°C before being suddenly and dramatically cooled by bursts of air. This produces clinker the basic material required for the production of all cements.
