Only by strictly limiting the content of Fe 2 O 3 in raw materials and fuels can we meet the production requirements of white cement. Therefore, white cement plants often use high-quality limestone as raw materials and mix with silica raw materials such as pyrophyllite, feldspar, silica, kaolinite, and quartz sand to produce white cement.

The test process was divided into the raw material preparation stage and the brick-making stage. In the raw material preparation stage, the muck was dried in an oven at 105°C for more than 24 hours; then a grinder was used to crush it to less than 0.25 mm in diameter. In the brick-making stage, the process of making unfired bricks can be divided into the raw material …

Clinker and cement production is an intensive process in terms of natural raw material and energy input. Limestone (primary source of calcium carbonate CaCO 3) and clay (primary source of silica SiO 2, alumina Al 2 O 3 and iron oxide Fe 2 O 3) are typically mined in company-owned quarries and pre-blended to a target chemical material composition.

There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite. The ore rocks are quarried and crushed into smaller pieces of about 6 inches.

The most common way to manufacture portland cement is through a dry method. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches.

Sulphur (S): A very small amount of sulphur is useful in making the sound of cement. If it in excess, it causes the cement to become unsound. Alkalies : The most of the alkalies present in raw materials are carried away by the flue gases during heating and the cement contains only a small amount of alkalies.
