However, new cement kilns are of the 'dry process' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the pre-heater tower. Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to heat the raw meal. As a result, the raw meal is already hot before it enters the

temperature, and gas components in a cement rotary kiln were obtained by numerical simulation of a 3000 t/d rotary kiln with a four-channel burner. A zone wise heat flux model was presented which accounted for the thermal enthalpy of the clinker formation process and gave more insight to fluid flow, temperature, etc. within the cement rotary kiln

This method is called a semi-dry process, which belongs to the cement dry process production. Advantages: as the dry process is to directly feed raw material powder into the rotary kiln for calcination, and the moisture content of raw materials is about 1% – 2%, it saves the heat consumption needed for the moisture evaporation

The rotary kiln dryer (rotary dryer) is a type of cement dryer employed to reduce the moisture content of cement raw materials. It works by drying materials through high-temperature gas in a rotating and slope drum. In the cement industry, no matter using dry or wet methods to produce cement, all kinds of water containing raw materials, coal and mixed materials need to be dried to ensure the normal operation of
