Cement Production: Raw Meal Production in Steps
The key word is quality! And this quality is achieved during cement production with exactly matched process steps. In the first stage, the raw meal is produced, as described below. Schenck Process measuring and feeding devices play a major role in this process. 1. Raw material production The raw meal is based on limestone which is mined at a quarry, crushed and temporarily stored in blending beds.
Raw materials for cement manufacturing
The second important raw material for cement production is clay.The main component of clay is formed by hydrous aluminium silicates.The stone composition of clay may vary from those close to the pure clay, to that containing a significant amount of admixtures as iron hydroxide, iron sulfide, sand, calcium carbonate, etc. Clay is used as an argillaceous component of raw mix.

Depending on its characteristics, the raw material needed for the cement production process is quarried by blasting, hydraulic excavators or ripping. A wide range of crushing plants – depending on the material’s properties and type of extraction – can be used for breaking the extracted raw material to the size required by the raw mill.
Manufacturing process | Lafarge - Cement, …
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 onto dumpers which transport the materials and unload into hoppers …
Cement Clinker Quality Control During Clinker …
During normal production process, the clinker is always calcined in a fixed temperature range. According to the fluctuation of raw meal composition, the calcination temperature of clinker is generally between 1350℃ and 1450℃. If the temperature in the kiln is too low, it is easy to produce underfired clinker.

The cement kiln
The basic dry process system consists of the kiln and a suspension preheater. The raw materials, limestone and shale for example, are ground finely and blended to produce the raw meal. The raw meal is fed in at the top of the preheater tower and passes through the series of cyclones in the tower. Hot gas from the kiln and, often, hot air from the clinker cooler are blown through the cyclones. Heat is …
