The heated raw meal now enters the kiln where the gas temperature exceeds 2000 °C, where it is transformed into a molten mixture inside the rotating kiln. At the temperature of 1450 °C the minerals in the raw meal undergo chemical reaction to form a new compound known as Clinker, which is the pre-curser for the production of cement.
Blend raw materials in a slurry state with 30%-50% water. The cement kiln size for clinker calcination is big. It is easy to obtain a homogeneous raw meal, so the clinker quality is higher. It generates little dust. The fuel consumption is high. More production costs. The establishment cost is comparatively high.

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.
Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.

Cement grinding Vertical roller mills versus ball mills. cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding.
The cement manufacturing process starts from the mining of limestone, which is the main raw material for making cement. Limestone is excavated from open cast mines after drilling and blasting and loaded on to dumpers which transport the material and unload into hoppers of the limestone crushers.
Ordinary Portland cement is the cementing material used in cement concrete hollow blocks. First of all, mix the cement, stone chips, sand, etc in the ratio of 1:6 or 1:12. This mixture is put in the vibrator machine. This is then poured into the desired size mold. After 24 hours of drying, put the blocks in the water tank for curing.
Cement Industry in Pakistan: At the time of partition in 1947, there were four plants producing 3, 30,000 tons of cement every year. However, in 1953 – 54 the production of cement rose to 6, 60,000 tons. In 1956 P. 1.D.C. set up cement factories at Daud Khel and Hyderabad.

The company opened its doors on January 28, 1952 and started commercial production a few weeks later on February 8th at an initial plant capacity of 100,000 tonnes of cement, and with a start-up capital of 1.2 million pounds.
Dec 01, 2017· Cement manufacturing has three key process steps: 1) Limestone from the quarry is crushed and appropriate raw material, like iron oxide, silica oxide, aluminum oxide, etc is mixed and ground to get the raw meal. 2) This raw meal is passed through the cement kiln at very high temperatures to produce clinker.
Dec 08, 2020· Although a cement factory is a growing and profitable business, it needs proper planning before you start executing. Starting a cement factory involves a lot of natural and unnatural factors. Natural factors involve things like raw material like limestone or power supply for which you need a reliable source like coal or proximity to the power grid.
