"Cement production refers to the process of crushing limestone, clay, coal and other raw materials, mixing them, calcining clinker, grinding, mixing, packaging and other processes, and finally making cement products.
Specific steps are as follows:
Mining and crushing of limestone and clay: Firstly, raw materials such as limestone and clay need to be excavated in the mine and crushed.
Raw material pretreatment: the mined raw materials are mixed, crushed, weighed, and sent to the production line.
Clinker firing: The pretreated raw materials are fired into clinker at high temperature, usually using a rotary kiln for firing.
Grinding: Grinding the fired clinker into a fine powder, usually using a ball mill for grinding.
Mixing: The ground cement clinker is mixed with auxiliary materials such as gypsum and slag.
Packaging: Make the mixed cement into bags or bulk products.
The above are the basic steps of cement production, and different cement manufacturers may have differences in specific process steps. It should be noted that a large amount of dust and exhaust gas may be generated during the cement production process, so corresponding environmental protection measures need to be taken to reduce the impact on the environment.
