What should I pay attention to when ordering a cement production line?

Production line equipment configuration:
Limestone is commonly used in the cement preparation process, but the mined limestone generally has a large particle size and needs to be crushed. Generally speaking, the processing of limestone into cement requires raw meal preparation and homogenization, coal powder preparation, clinker calcination and cement grinding. Stage.
1. Raw meal preparation and homogenization: natural limestone, clay and peculiar raw materials are crushed by a jaw crusher and mixed in a certain proportion, and then ground by a ball mill to prepare raw meal with suitable composition and uniform quality;
2. Preparation of pulverized coal: The coal required for calcining cement raw meal must be prepared into pulverized coal to provide the required particle size for pulverized coal combustion, so as to be fully burned and obtain sufficient combustion reaction capacity. In this process, coal powder can be fed directly, and equipment such as jaw crushers and ball mills will be used for processing.
3. Clinker calcination: the lime raw meal is calcined in a rotary kiln until it is partially melted to obtain lime clinker.
4. Cement grinding: the clinker is added with appropriate amount of gypsum, admixtures or additives to grind into cement together, and packaged and shipped.
