Grey Portland Cement Manufacturing Process

 





 



 






Products Description




 









How is Grey Portland cement made?



 



Crushing, batching, calcination, cooling, and grinding are some of the steps used to make Portland cement, a hydraulic cementing substance composed of clay and limestone. Its excellent strength and numerous uses have made it one of the most often utilized forms of cement in contemporary construction projects.



 



Our high-efficiency Portland cement production line consists of the following key steps: 1. crushing, proportioning, and blending of raw materials; 2. grinding of raw materials; 3. preheating and calcination; 4. cooling and grinding of clinker; and 5. packing and shipping of cement. Jaw and impact crushers, raw material vertical mills, cement ball mills, preheating systems, cement rotary kilns, packaging machines, and more are among the main pieces of equipment used throughout the entire production process. Our company can supply all of the cement equipment needed for this production line.

How To Use Our Grey Portland Cement Production Line




 





 



1.Raw Material Crushing, Proportioning&Blending

The large raw materials such as quarried limestone and clay are crushed into appropriate particle sizes suitable for subsequent processing using crushers. After the mixing process, the crushed and preliminarily homogenized materials are thoroughly combined, ensuring all components are evenly distributed and fully blended. This allows the quality of raw materials from different batches to become more stable.



 



2.Raw Material Grinding

Grinding raw materials is a crucial step in the production of grey Portland cement.Raw materials that have already been crushed and homogenized are further ground into incredibly fine powders in this step.During the grinding process, various raw materials (such as limestone, clay, iron ore powder, etc.) are carefully mixed in exact ratios to ensure that the chemical composition of the raw meal is uniformly constant. After being ground, the raw meal powder that meets the requirements is sent to a storage silo to await the calcination process.



 









3.Preheating&Calcination


 



The raw materials are first sent into a preheater, which is typically composed of piping, cyclones, and heat exchangers. Through efficient heat exchange and airflow organization, the raw materials are heated to about 800°C, removing moisture and improving their burnability. The preheated and dried raw materials are then fed into a rotary kiln, which is the core equipment for the calcination process. The rotary kiln is usually made of refractory materials and equipped with devices such as burners, cooling units, and sealing systems. Under high temperatures, the raw materials undergo physical and chemical changes, forming cement clinker.












4.Clinker cooling&grinding



Clinker enters the cooler, where it is cooled to around 150°C through ventilation or spray cooling, in order to prevent changes to the internal crystal structure of the cement clinker. The cooled clinker then proceeds to the grinding stage, where it is ground into powder form using a ball mill, in preparation for subsequent storage, packaging, and transportation.










5.Cement Packing&Transportation







 



Finally, Portland cement enter packaging process, and then they can be loaded for transportation.
