I. Crush and pre-homogenization Crush. In cement production process, most of raw materials must be crushed, for example, limestone, clay, iron ore, coal, etc. In cement production, limestone is the main raw material whose amount is the largest in all the raw materials.

The ability to crush sticky materials allows the simultaneous feeding of several materials by means of two or three apron feeders, causing a pre-homogenization within the crusher. Other crushers Double Roll Crusher and RollSizer. Despite of their low crushing ratio both Double Roll Crusher and RollSizer are used in the Cement and lime Industry.

Clinkering is the primary step in the cement manufacturing process. The function of the kiln in the cement industry is to first convert limestone into lime, then react it with silica, aluminum oxide, and ferric oxide to form clinker compounds: C 3 S, C 2 S, C 3 A, and C 4 AF. The kiln is the heart of this production process.

Summary：In brief, cement production has the following 7 steps: crushing and pre-homogenization, raw meal preparation, homogenization of raw meal, preheating decomposition, firing of cement clinker, cement grinding and cement package. Cement is a powdery hydraulic inorganic cementing material. After adding water and stirring, it becomes slurry, which can harden in the air or in …

3.Production Process In the cement produciton line,it contains 8 parts:raw materials,raw material preparation,crushing and pre-homogenization,raw material homogenization,pre-heater and calciner,the burning of concrete clinker,grinding and concrete packging. 4.What is the main equipments in the cement production line?

The pre-homogenization process makes the materials storage and homogenization. 2, The prepare and homogenization of cement raw meals In the cement production process, every production of 1 ton of Portland cement grinding at least needs 3 tons of materials (including raw materials, fuel, clinker, mixed materials, gypsum).

two separate Cement Production lines can be summarized into the following processes ;as can be seen in the process and Quality flow diagram below; 1. Quarrying and Crushing 2. Raw material Storage and Transportation 3. Proportioning 4. Raw material Grinding and Transportation 5. Raw meal storage, homogenization and Kiln feeding 6.

Raw meal homogenization is a process in which the ingredients of the ground raw meal tend to be uniform through reasonable matching or pneumatic mixing. The raw meal preparation process of the cement industry includes four links: mining, pre-homogenization, grinding, and homogenization, which form the homogenization chain of raw meal preparation.

Homogenization (BLENDING) In preparing raw meal, raw materials like limestone, clay and iron ore are proportioned and fed to raw mill, where these raw materials are ground and well mixed. However, this mixing is not enough to produce clinker of uniform quality. For stable kiln operation and to obtain uniform quality of clinker it is necessary ...
