Find out more about our main types of cement.. Cement is the most widely used construction material worldwide. It provides beneficial as well as desirable properties, such as compressive strength (construction material with highest strength per unit cost), durability, and aesthetics to a variety of construction applications.
We use alternative raw materials for the production of clinker, which is the most important intermediate product in the manufacture of cement. In this way we reduce the amount of CO 2 intensive clinker in the final product. The increased use of alternative raw materials in cement production is thus a core element of our climate strategy. At Group level, the proportion of clinker in cement amounted to % in 2017.
RAW CEMENT GRINDING This phase of grinding may be either the wet or dry process, the end product going to a kiln. Material ground consists of limestone, cement rock, marl or marine shells along with secondary materials usually shale or clay.
(1) Crushing: during the process of producing the cement, the majority of materials are needed to be crushed, such as the limestone, clay, iron ore, coal, etc. Limestone is the most commonly used raw material, with large particle size and high hardness after crushing.

Cement plants continue to seeks ways to reduce fossil fuel consumption through use of alternative fuels. Clinker substitution with limestone or pozzolanic additives is now a common practice. Cement Industry Services. Onsite review of material flow problems; Raw material, additive, cement flow testing; Silo and feeder design for all bulk materials
Reliable equipment means equipment designed to handle the raw materials it will be processing. That's why raw material specifications are so important. Looking at the four basic parameters – feed and product size, abrasiveness, compressive strength, and stickiness – will help cement plant owners choose the right stackers and reclaimers.
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.
Some typical materials used for calcium carbonate in cement manufacturing are limestone, chalks, marbles, marls, and oyster shell. Some typical materials used for alumina in the cement manufacturing are shale, clay, slags, fly ash, bauxite, alumina process waste, and granite.
To meet ever increasing demands, cement kilns must have consistent, reliable feed of raw materials, such as limestone, clay, sand, mill scale/iron ore, and bauxite. Though dry process cement plants are advantageous over wet process plants due to significant energy savings, they experience additional material handling problems during feeding, milling, and calcination.
Calcination. Calcination is the core portion of the process, in which huge rotary kilns come into play. Inside, at 1400 degrees C, the raw material is transformed into clinker: small, dark gray nodules 34 centimeters in diameter.
The recommended amount of wastes to be used is the amount that is determined carefully in a way that when it is mixed with the conventional raw materials, it does not disturb the specifications of the produced cement. "The solid waste raw materials that are proposed for coprocessing in cement plant, must meet the quality specifications ...
