Classification of Rotary Kilns


Type of wet rotary kiln

The cement kiln used in wet production is called wet kiln. Wet production is to make raw meal into slurry with water content of 32%~40%. As the slurry with fluidity is prepared, the raw materials are well mixed, the raw meal composition is uniform, and the quality of sintered clinker is high, which is the main advantage of wet production.

Type of dry process rotary kiln

The advantages and disadvantages of dry process rotary kiln are opposite to those of wet process rotary kiln. The dry method makes the raw meal into dry powder, and the water content is generally less than 1%, so it reduces the heat required for evaporation of water compared with the wet method. The heat consumption of hollow kiln is not low due to the high temperature of waste gas. In dry production, raw meal is made into dry powder, and its fluidity is worse than that of slurry. Therefore, the raw materials are poorly mixed and the ingredients are uneven.
