Cement rotary kiln Choose refractory or stainless steel shell according to temperature requirements

Cement rotary kiln classification:

1. Types of wet cement kilns:

The cement kiln used in wet production is called wet kiln. Wet production is to make raw materials into slurry with a water content of 32%~40%. Because it is prepared into a fluid mud, the raw materials are well mixed, the raw material composition is uniform, and the quality of the burned clinker is high, which is the main advantage of wet production.

2. Types of dry cement kilns:

Compared with wet rotary kilns, the advantages and disadvantages of dry rotary kilns are exactly the opposite. The dry method makes raw materials into raw material dry powder, and the moisture content is generally less than 1%, so it reduces the heat required to evaporate moisture compared to the wet method. The heat consumption of hollow kilns is not low due to the high exhaust gas temperature. Dry production makes raw materials into dry powder, and its fluidity is worse than mud. Therefore, the raw materials are not mixed well and the composition is uneven.

Performance characteristics of cement rotary kilns

1. Structural advantages

The structure is strong and the operation is stable.

2. Wide range of applications

In addition to calcining cement clinker, it is also used to calcine clay limestone, dry slag, etc. In the production of refractory materials, rotary kilns are used to calcine raw materials to stabilize their size and increase their strength, and then process them into shape.

3. High environmental benefits.

Using cement kilns to incinerate hazardous waste and garbage not only reduces the amount of waste and makes it harmless, but also uses waste as fuel, saves coal powder, and achieves waste resource utilization.
