    To manufacture 1 t of Portland cement, about 1.5 to 1.7 t raw materials, 0.1 t coal and 1 t clinker (besides other cement constituents and sulfate agents) must be ground to dust fineness during production. In this process, the steps of raw material processing, fuel preparation, clinker burning and cement grinding constitute major emission sources for particulate components. While

    The raw material preparation stage of cement manufacture results in the production of a rawmix that is in a suitable state for feeding to the kiln in which it is converted by heat into clinker. This is a chemical transformation. The rawmix consists of a mixture of materials that will react together to form the calcium silicates that confer on the clinker its strength-giving properties. The ...

    In the large rotary kiln, the raw material is converted into clinker at 1450 degrees Celsius. 4. The clinker enters the grate cooler from the kiln head for thermal regeneration and cooling. The cooled clinker is then transferred to the clinker bin for storage using a tray conveyor. 5. After clinker is cooled, it can be transported on the conveyor belt and can regenerate up to 30% of heat. The ...

    The cement kiln heats all the ingredients to about 2,700 degrees Fahrenheit in huge cylindrical steel rotary kilns lined with special firebrick. Kilns are frequently as much as 12 feet in diameter—large enough to accommodate an automobile and longer in many instances than the height of a 40-story building. The large kilns are mounted with the axis inclined slightly from the horizontal.

    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 ...

    The blended raw materials are stored in a silo before being fed into the kiln. The silo stores several days' supply of material to provide a buffer against any glitches in the supply of raw material from the quarry. 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 ...
