rotary kiln cement plant,
cement production plant
High availability low price rotary kiln for cement kiln and clinker plant
cement plant introduction
We provide the full range service including design, manufacturing, installation. We design and manufacture equipment for new type dry method cement production line, for which the capacity varies from 50t/d to 3000t/d
Mined limestone is delivered to the crusher for crushing by the belt conveyor, limestone after crushing ,clay, iron powder etc will be ground into powder by ball mill or vertical mill, and then transported by air delivery chute to raw meal homogenization silo for storing and further material mix. Raw meal shall get into the preheating decomposition system after homogenization where decomposition rate is about 95%, and raw meal is calcined into clinker in the rotary kiln, the formation of clinker. Clinker, gypsum and mixture is ground into qualified fineness cement in the cement mill. Powder classifier is adopted to adjust the fineness of cement, realizing energy saving production. Cement packing machine and automatic loading machine are used for bagged cement delivery, and cement bulk device for cement canning leaving factory.
1. Crushing and Pre-homogenizing:
Most of the raw materials, like limestone, clay, iron ores, and coal, should be crushed before their pre-homogenization. Limestone is the primary material in this line, and due to its large particle size and high hardness, its good crushing plays an important role in the whole line. Special stacking and reclaiming technology has been used in the pre-homogenizing process so that raw materials can be better primarily homogenized.
2. Raw Meal (raw material) Preparing:
Since the raw meal grinding work takes up more than 30% labor force in the whole dry process cement production line, it is quite important to choose appropriate grinding equipment and technological process so that high-quality products can be obtained.
3. Raw Meal Homogenizing:
The raw meal homogenization is a key factor for stable clinker calcination.
4. Preheating and Decomposing:
The preheater is used to preheat as well as decompose raw meal. So the length of the rotary kiln is effectively shortened. And the raw meal can fully exchange heat with the hot gases from the kiln. Because of its rapid and high-efficiency heat transfer, the production efficiency and heat consumption of this production line are greatly improved.
5. Clinker Calcining:
After its preheating and pre-decomposing, the raw meal will be calcined in the rotary kiln, where the generated carbonate will be further decomposed. Meanwhile, a series of solid phase reactions will take place.
