  • Cement firms oppose attempts at raising clinker import

    Mar 04, 2020· Clinker is currently charged 10 per cent duty as per East Africa Community Common External Tariff regime for raw materials. Companies opposed to the duty increase say it will be a contravention of the EAC Common Market protocol and could kill competition.Cement clinker Wikipedia,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.

    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(PDF) Analysis of material flow and consumption in cement,The results show that approximately 2.48t, 4.69t, and 3.41t of materials are required to produce a ton of the product in raw material preparation, clinker production, and cement grinding stages

  • Vertical Roller Mills Fruitful

    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 and product quality.

The majority of Portland cement clinker manufactured around the world has a lime saturation of between 90 and 100%. This means that c.1.55 tonnes of raw mix are required and c.0.55 tonnes of CO2 are lost due to calcination of the CaCO3 in the raw material. The clinker factor is therefore 0.65 x the amount of raw mix. Reply
