At the final stage, cement is packaged into bags and ready to produce concrete. The first step in the process of making concrete is mixing cement, water, sand and gravel in the proportion of 15%, 10%, 25% and 50% respectively. This mixture is then put into a concrete mixer to produce concrete, which is used for building purposes.
2. Transporting the raw material. Once the huge rocks have been fragmented, they are transported to the plant in dump trucks or by conveyor belt. 3. Crushing. The quarry stone is delivered through chutes to the crushers, where it is reduced by crushing or pounding to chunks approximately 1 ½ inches in size. 4.

(VI) ALKALIES: It causes the cement efflorescent. MANUFACTURING PROCESSES: There are two manufacturing processes (i) Dry Process (ii) Wet Process Dry Process: If raw material is hard and dry then this process is used for preparation. Process :
Cement Manufacturing Process Flow Chart (i) Drying Zones: In the wet process, the drying zone is comparatively larger than the dry process. It is because the raw material in slurry form is directly fed into the kiln which has more amount of water. As shown in the figure it is the upper portion of the kiln.
A diagram of the process, which encompasses production of both portland and masonry cement, is shown in figure 1 below, the process can be divided into the following primary …
In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The …

All the cement plants set up after 1980 use the dry process for the manufacture of cement. In this process, the calcareous materials such as limestone are crushed and stored in silos or storage tanks. The argillaceous material such as clay is thoroughly mixed with water in a container known as the wash mill. This washed clay is stored in basins.
Finally, during the cement grinding and distribution process, firstly the cooled clinker is ground with around 5% of gypsum and other 17 JRTE-2020 cementitious materials to form the final...
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.
Manufacture of cement – consists of mixing, burning, and grinding processes. 1. Mixing: It may be a wet process or by dry process. In a wet process wash mill is used which is a heavy cylinder of 2.5 to 3.0 m in diameter and 9 to 12 m in length. It is kept slightly inclined to the horizontal and can rotate at 15–20 revolutions per minute.

The process of manufacture of cement consists of grinding the raw materials, mixing them intimately in certain proportions depending upon their purity and composition and burning them in a kiln at a temperature of about 1300 to 1500°C, at which temperature, the material sinters and partially fuses to form nodular shaped clinker.
