There are four stages in the manufacture of portland cement 1 crushing and grinding the raw materials, 2 blending the materials in the correct proportions, 3 burning the prepared mix in a kiln, and 4 grinding the burned product, known as quotclinker,quot.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.Feb 03, 2021 Water and crushed rock, sand, and gravel, which are used as aggregates, are the main raw materials used in PC concrete manufacturing. Approximately 6 of CMs cycle emissions arise from extraction. 3.2 Production. PC production involves crushing and grinding, pyro‐processing, and grinding and blending.Materials are extracted quarried recovered and transported to the cement plant. 2 Crushing and milling. The raw materials, limestone, shale, silica and iron oxice are crushed and milled into fine powders. 3 Mixing and preheating. The powders are blended (the ‘raw meal’) and preheated to around 900 C using the hot gases from the kiln.
