Cement
Raw materials are extracted from slingshots and quarries. Then, the raw materials are transported using conveyor tapes or cars to the factory. Grinding the raw materials, according to studied proportions, and chemical analyzes, to increase the surface area of the granules, and they are ready to enter chemical reactions. The ground raw materials are incinerated in rotary kilns, at high temperatures, and converted into clinkers. Packaging of ready-made cement in plastic or paper bags.Raw materials, from silicates, limestone, clay, and surface earths are crushed using crushers, and transported to the factory for storage in open or covered areas, and their later use. Then the raw materials are grinded, using suspension mills, and mixed with water, and the grinding process continues until the texture of the raw materials becomes smooth. Then the ground materials in the suspensions are conveyed to storage silos, to adjust the final shape, and get a homogeneous mixture. Taking a sample of the mixture periodically and examining it, to ensure that the mixture matches the required specifications. Transfer the mixture to the suspended basins, and there the mills turn it into a homogeneous mixture. Draw the homogeneous mixture inside the suspensions from the inside of the sink into the feed hole of the rotary kiln, which is a long cylindrical ovenSlightly inclined from the horizontal to push the oven contents while rotating forward, and lined with refractory bricks on the inside. The mixture was dried in the oven by the action of high combustion gases, then the clinker was cooled by air cooler. Transfer the dry mix to kor mills, add gypsum to it, and grind it final. Cement packing in bags.
