Brief Introduction of Production Line

The cement production line uses limestone and clay as the main raw materials, which are crushed, batched, and ground to make raw materials, which are then fed into the cement kiln to calcinate mature materials, and then the clinker is ground with appropriate amounts of gypsum and mixed materials.

Cement production equipment varies with raw meal preparation methods, and can be divided into dry cement production lines and wet cement production lines (including semi-wet method).

Dry cement production process. The raw materials are dried and ground at the same time, or the raw materials are dried and ground into raw meal powder and then fed into the dry process kiln to calcinate mature materials. However, there is also a method of adding raw meal powder into a proper amount of water to make raw meal balls, and then sending them into the Liboer kiln to calcinate the mature material. This method is called semi-dry method, which is still a dry method. Wet cement production process. The raw material is ground into raw material slurry by adding water powder, and then fed into wet kiln to calcinate mature material. There is also a method of dewatering the raw material slurry prepared by the wet method, and then making the raw material block into the kiln to burn the mature material, which is called the semi-wet method, which is still a kind of wet method production.

Features

The main advantage of dry production is low heat consumption (for example, the heat consumption of dry kiln with preheater is 3140~3768 J/kg). The disadvantage is that the raw meal composition is not easy to be uniform, the workshop dust is large, and the power consumption is high. Wet production has the advantages of simple operation, easy control of raw meal composition, good product quality, convenient slurry transportation, and less dust in the workshop. The disadvantage is high heat consumption (the heat consumption of clinker is usually 5234~6490 J/kg).
