RAW MATERIALS IN CEMENT PRODUCTION Primo Pizza

The choice of composition of materials mixture with useful components generally is determined by plant’s geographical location and delivery of raw materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.

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.

CEMENT RAW MATERIALS International Cement Review

The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level

The discharged raw mix (limestone 70%, clays 30%) is conveyed to a raw mill bin for later grinding. The other raw materials that are used in cement manufacturing, called additives, are also stored in separate bins. 3. Drying and grinding. The raw mix and required additives are fed from their bins to the raw mill via blowers for drying and grinding.
