Detailed Description
Process of cement production line:1. Raw MaterialsThe main raw materials used in the cement manufacturing process are limestone, sand, shale, clay, and iron ore. The main material, limestone, is usually mined on site while the other minor materials may be mined either on site or in nearby quarries. Another source of raw materials is industrial by-products. The use of by-product materials to replace natural raw materials is a key element in achieving sustainable development.2. Raw Material PreparationMining of limestone requires the use of drilling and blasting techniques. The blasting techniques use the latest technology to insure vibration, dust, and noise emissions are kept at a minimum. Blasting produces materials in a wide range of sizes from approximately 1.5 meters in diameter to small particles less than a few millimeters in diameter.Material is loaded at the blasting face into trucks for transportation to the crushing plant. Through a series of crushers and screens, the limestone is reduced to a size less than 100 mm and stored until required.Depending on size, the minor materials (sand, shale, clay, and iron ore) may or may not be crushed before being stored in separate areas until required.3. Crushing and Pre-homogenization.Crushing. During producing Concrete, most of the raw materials must be first crushed before being used to make concrete. Among these raw materials which include lime stone, clay, iron ore and coal, etc. The lime stone is of the greatest usage to make concrete. With comparatively larger particles and higher hardness, crushing the lime stone to required fineness after mining is of relatively important consequence among crushing all those raw materials.There are many crushers used in crushing these raw materials, such as jaw crusher, impact crusher, cone crusher and vertical shaft impact crusher, etc. According to the raw materials' different particles and hardness, there are several suitable crushers which can be used in the crushing.Pre-homogenization of raw materials.4. Raw material Homogenization.In the process of new dry concrete production, the stability of pit entry clinker raw material component is the premise of the whole system. Raw material homogenization system plays very important role in the stability of pit entry clinker raw material component.5. Pre-heater and calciner6. The burning of concrete clinker.7. GrindingGrinding is the last process of cement produce and also is the most current consuming working procedure. Cement clinker get grinded into the right size. The smaller the particle size is, the better the final cement is. It's important to choose suitable grinding machine.8. Concrete Packaging.
