Raw materials used for cement manufacturing. Cement manufacturing is an energy and resource intensive process. It involves closely controlled chemical reactions between calcium silicate minerals at high temperatures of above 1400 degree Celsius. In this process, chemical bonds of key raw materials – limestone, shell, chalk, sand, clays ...
As shown in the figure, the process can be divided into the following primary components: raw materials acquisition and handling, kiln feed preparation, pyro-processing, and …
Stage of Cement Manufacture. 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 …
5. Raw material storage. Each of the raw materials is transported separately to silos, where it later will be added in specific amounts according to the particular type of cement being produced. 6. Raw material mill. This takes places in vertical steel mill, which grinds the material through the pressure exerted by three conical rollers.
installed on Cement Mill 3 (CM3), a 100tph ball mill that is used for the production of high-quality and special cements using a hybrid third-generation separator. Following the successful roll-out on CM3, the system has now been installed on the plant's two additional cement mills (CM2 and CM4), as well as the raw materials

The desired raw mix of crushed raw material and the additional components required for the type of cement, e.g. silica sand and iron ore, is prepared using metering devices. Roller grinding mills and ball mills grind the mixture to a fine powder at the same time as drying it, before it is conveyed to the raw meal silos for further homogenisation.
Step 1: Mining. 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. The limestone is excavated from open cast mines after drilling and blasting and loaded ...
How Cement Is Made. Watch on. 1. Mining the raw material. Limestone and clay are blasted from rock quarries by boring the rock and setting off explosives with a negligible impact of the environment, due to the modern technology employed. 2. Transporting the raw material.
