Raw materials - Understanding Cement
The most common raw rock types used in cement production are: Limestone (supplies the bulk of the lime) Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide) Other supplementary materials such as sand, fly ash/pulverised fuel ash (PFA), or ironstone to achieve the desired bulk composition.
What is Cement Clinker? Composition, Types & Uses - Civil ...
silica fume cement; Clinker is primarily used to produce cement. Since it can be stored in dry condition for several months without noticeable deterioration, it is traded internationally in large amounts. Cement manufacturers buy clinker for their cement plants in areas where raw materials for cement are scarce or unavailable.
CEMENT RAW MATERIALS - cemnet.com
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.

Portland cement clinker - Understanding Cement
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.
Difference between Clinker and Cement - Civil Engineering
The primary use of clinker is to manufacture cement. Cement is used in construction to make concrete as well as mortar and to secure the infrastructure by binding the building blocks. It is also used for water-proofing, filling or sealing gaps, and making decorative patterns.

Apr 30, 2017 · Portland cement clinker is the material that gets ground up (possibly with gypsum and other small quantities of material) to become Portland cement. Clinker is in the form of rounded granules, typically 3 to 25mm diameter. Those granules are the sintered output from large rotary kilns.
How Cement Is Made
Cement is manufactured through a closely controlled stone combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

Rawmill - Wikipedia
A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The raw milling stage of the process effectively defines the chemistry of the finished cement, and has a large effect upon the efficiency of the whole manufacturing process.
