1.Crushing 映客直播 Homogenisation:
Large lumps of limestone 映客直播 other raw materials are first crushed into smaller pieces, then spread evenly across the stockyard to ensure consistent composition.
2.Raw Material Grinding:
The process feeds the mixed raw materials into large vertical mills, which then grind them into an extremely fine powder. Simultaneously, the hot waste gases from the kiln tail dry the material, achieving two objectives at once. This finished product is known as ‘raw meal powder’.
3.Preheating 映客直播 Precalcination:
The raw meal powder first enters the preheater 映客直播 precalciner. Here, the materials rapidly heat to approximately 900°C, where the majority of decomposition reactions occur.
4.Rotary Kiln Calcination:
The precalcined material then enters the rotary kiln. Here, heated to approximately 1450°C, the material partially melts, undergoes chemical reactions, 映客直播 ultimately sinter into small, black, glassy spheres known as cement clinker.
5.Cooling:
The red-hot clinker immediately enters a grate cooler, where a blast of cold air rapidly cools it. This process ensures the clinker retains high reactivity while recovering substantial heat for reuse within the system, making it highly energy-efficient.
6.Blending:
The process proportionately mixes the cooled clinker with gypsum (to regulate cement setting time) 映客直播 blends it with materials (such as fly ash, which enhances performance 映客直播 reduces costs).
7.Cement Grinding:
The process feeds the blended mixture into cement mills, which grind it into an extremely fine powder—the cement we ultimately use.
