Clinker quality depends on raw material composition.

Jan 14, 2014  By Darrell Leetham 01.14.2014. Clinker quality depends on raw material composition. Portland cement is the most common type of cement in the world. It is used primarily to make concrete, mortar, and grout. Portland cement manufacturing begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called ...

What is Cement Clinker? Datis Export Group

Jun 18, 2020  Clinker is a granular substance containing spherical pellets of diameter 3-25 mm. Cement is such a fine powdery substance that each pound of cement contains 150 billion grains. 3. Clinker is produced inside the kiln during the cement manufacturing process. Raw mix is heated and then rapidly cooled to produce the marble-sized pellets of clinker.

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

Cement clinker - Wikipedia

The Portland clinker essentially consists of four mineral phases: two calcium silicates, alite (Ca3Si) and belite (Ca2Si), along with tricalcium aluminate (Ca3Al) and calcium aluminoferrite (Ca4AlFe). These main mineral phases are produced by heating at high temperature clays and limestone. Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kilnat high temperature. The products of the chemical reaction aggregate together at their sintering temperature, a
