· Wet process. 1. When chalk is used, it is finely broken up and dispersed in water in a washmill. The clay is also broken up and mixed with water, usually in a similar washmill. The two mixtures are now pumped so as to mix in predetermined proportions and pass through a series of screens. The resulting – cement slurry – flows into storage tanks.
Manufacturing the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...

Manufacturing Process. Portland cement a combination of calcium, silica, aluminum and iron is the fundamental ingredient in concrete. Producing a calciumsilie Portland cement that conforms to specific chemical and physical specifiions demands careful control of the manufacturing process.
Wet process. 1 Mixing of Raw materials in wash mill with 35 to 50% water. 2 Materials exiting the mill are called "slurry" and have flowability characteristics. 3 Size of the kiln needed for the manufacturing of cement is bigger. 4 Raw material can be mixed easily, so .
View the interactive animation of the cement production process to learn how cement is made by CEMEX. 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.

Portland cement companies combat heavy dust, reclaim product and enhance quality control using a variety of vacuum cleaning appliions. In an industry that has its roots in ancient Roman times, and turns mountains into dust with rugged equipment that pounds, crushes, and grinds, a vacuum cleaner seems almost unnatural—a little domestic.
The initial production step in portland cement manufacturing is raw materials acquisition. More than 30 raw materials are known to be used to manufacture portland cement. Calcium, the element of highest concentration in portland cement, is obtained from a variety of calcareous raw materials, including

Type O: Portland cement clinker + mixture of Alite, CaO, and anhydrite. In this case, the expansion results from the hydration of the free lime. The CaO is present largely as inclusions within the alite grains and undergoes hydration more slowly as the alite hydrates, resulting in controlled expansive properties.
