Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties.
Clinker In the manufacture of portland cement, clinker is lumps or nodules, usually 3-25 mm in diameter. Portland cement clinker is made by heating in a rotary kiln at high temperature ( 1450 °C ) a homogeneous mixture of raw materials. The major raw material for the clinker-making is usually limestone (CaCO3) and alumino-silicate.

Portland Cement Clinker is an important component of Portland cement. Portland cement is attained by grinding clinker with few amounts of a few other minerals; thus, its structure does not depart far from that of clinker. Although the other potential ingredients may be inexpensive natural materials, clinker is made in a kiln which is an [.]
Portland blast-furnace slag cement, or Blast furnace cement (ASTM C595 and EN 197-1 nomenclature respectively), contains up to 95% ground granulated blast furnace slag, with the rest Portland clinker and a little gypsum. All compositions produce high ultimate strength, but as slag content is increased, early strength is reduced, while sulfate ...
One clinker sample was analyzed 10 times to test the reproducibility of the free-lime channel. The results are summarized in table 2.

A source of free lime is introduced into a cooling zone of a cement kiln in an amount to elevate the free lime content to a content of 0.6 to 2.0%, by weight. This addition is made without altering the normal or standard process operating parameters of the kiln for cement clinker production. The free lime content of 0.6 to 2.0%, by weight, provides advantageous characteristics in cement ...
Cement is a finely milled mineral powder, usually grey in colour. The most important raw materials for the production of cement are limestone, clay, and marl. Mixed with water, cement serves as an adhesive to bind sand, gravel, and hard rock in concrete. Cement hardens both in the air and under water, and remains in its hardened state once reached.
Oct 15, 2015· Conveying cement clinker from clinker coolers to clinker storage to finish grind ing mills is part of the cement making process that all cement plants have to do. When the clinker is cool, conveying is a simpler process; conveying belts can be used. But when the clinker is hot, the methods for conveying become more limited, typically done with ...
